Triton_Mgn says,,, Good afternoon, give the antenna a good antenna for the 1800 MHz mimo Found 2 antennas on the forum: 1 - http://www.lan23.ru/forum/showthread.php?t=12671 But, unfortunately, not its size at the desired frequency, tell me who knows. 2 - http://www.lan23.ru/forum/showthread.php?t=10879 Could you tell me the thickness of the disc, can I use galvanized? In the drawing, the antenna of this size for the lower frequency 1747,5 pink color, and upper 1842,5 green. Why, then, in the drawing there are dimensions in blue? My answer is,, it can build a patches antenna instead of a disks, a horizontal patch antenna group (at one end of the frequency band) and the other group with vertical polarization (at the other end of the frequency band)

There are two types of antennas, RHCP, and the LHCP. Don’t be overwhelmed, it’s easy, we’ve outlined the basics below. RHCP antennas are known in full as Right Hand Circular Polarized antennas. LHCP antennas are known in full as Left Hand Circular Polarized antennas. Sometimes, they are both known simply as Circular Polarized (CP) antennas. Due to its polarized nature, this type of antenna will reduce any radio interference by a process known as multipathing. This blocks out unwanted radio signals and can give a much cleaner signal. For which below I was looking to do a simulation of the antenna after the Iulian Rosu site ... ??? https://qsl.net/va3iul/Antenna/Printed_and_Microstrip_Antennas/Design_Ideas_for_Printed_and_Microstrip_Antennas.htm

A horn antenna is one of the most commonly used antenna types for a focused antenna. However, the horn antenna is limited by its dimensions, which must have a certain size relative to the wavelength in order to work properly and efficiently. Since this will typically be too large to fit into the flange, a dielectric lens antenna with reduced dimensions is developed. The lens has the spherical form which is able to enhance the gain by making use of guided surface waves. The antenna is fed by a circular waveguide and at the boundary of the dielectric half space. A stepped impedance transformer has been introduced in order to provide broadband input matching impedance. Dielectric rod antennas refer to traveling wave antennas with a slow phase velocity (vf< s). They are used at the border of the centimeter and decimeter wave ranges in the frequency band from 2 to 10 GHz. Dielectric lenses are made of materials with high dielectric constants, such as polystyrene, polyethylene, and plexiglass. They can be integrated with various types of feeds, such as horn antennas, microstrip antennas, and waveguide antennas.

Two long arms are connected in the shape of V to make a V-antenna. The two long arms are excited with 180˚ out of phase. As the length of these arms increases, the gain and directivity also increases. The following figure shows a V-antenna with the transmission line impedance z=200 Ohm and the lengh of the arm 0,8*lambda, making an angle Φm with the axis, which is called as apex angle.material-FR4 #1.5mm. The main advantage of a V-shaped antenna is its relatively small vertical radiation angle, which is especially important for establishing long-distance communications.

This project is dedicated to Doyt R. Hoverman (b.1913), the man who created and did the early work on the Hoverman antenna at a time when antenna modeling programs did not exist. His work would have been entirely created and improved by field testing, trial and error, and with a great amount of calculation without the benefit of electronic devices. Without his efforts, our work would not have been. Doyt Hoverman passed away in December, 1989 at Van Wert, Ohio, USA. Technical data Simulation With insulating spacers

The modems have LTE parameters LTE connection. To determine the quality of the signal, note the following fields: — Signal strength — RSRP — RSRQ — SINR — CQI The following table shows the different values of these parameters, which correspond to very poor (Cell Edge), bad (Mid Cell), good (good) and very good (Excellent) the signal quality of the LTE: Next, briefly explain each parameter, which determines the quality of the LTE signal. The power of the signal The signal power shows the level of the received modem signal LTE. These values correspond to the readings of RSSI (Received Signal Strength Indication) of the LTE connection. The value is measured in dBm (dBm). Usually routers have indicators if it means burning the maximum -90 dBm or higher (tends to zero). If any indicator is not lit, then the signal level is insufficient for the connection to the LTE network. When the values of RSRP= -120 dBm and below, the LTE connection may be unstable or not installed. RSRP RSRP (Reference Signal Received Power) is the average value of the power taken by the pilot signal (Reference Signal) or the level of the received signal from the Base Station(BS) The RSRP value is measured in dBm (dBm). The signal strength of the LTE modem can also be defined using the SIGNAL STRENGTH indicators on the top panel of the device. The maximum level correspond to three burning indicator. If any indicator is not lit, then the signal level is insufficient for the connection to the LTE network. When the values of RSRP= -120 dBm and below, the LTE connection may be unstable or not installed. RSRQ RSRQ (Reference Signal Received Quality) determines the quality of received pilot signals. The value of RSRQ is measured in dB (dB). SINR SINR (Signal to Interference + Noise Ratio), also known as CINR (Carrier to Interference + Noise Ratio) – the ratio of the level of useful signal to noise level (or signal/noise). The value of SINR is measured in dB (dB). It's simple: the higher the value, the better the signal quality. When the values of SINR below 0, the connection speed will be very low, because this means that the received signal noise more than the useful part, while the probability of loss of the LTE connection also exists. CQI CQI (Channel Quality Indicator) For each subscriber station UE (User Equipment) and each frequency carrier block formed quality indicators channel CQI (Channel Quality Indicator). Depending on the required for UE speed data transmission the base station, the decision on the number of resource blocks allocated to a particular user, and what frequency blocks to allocate to the user depends on the indicator CQI. Users are allocated to those resource blocks that have the highest CQI, and therefore, the best ratio signal/noise. This parameter can take values from 0 to 15. The higher the value, the better (the higher the speed that can be allocated by the base station operator LTE). The most important first column — the value of RSRP. For example, we got to the target BS, the average is about -90 dBi. When determining the direction on the BS used a Yagi antenna with gain (KU) 12 dBi. Antenna cable, length 5 m "eats" on the attenuation of about 1.5 dBi, add about the same number of losses at the connectors — a total of 3 dBi. Accordingly, the default level of the signal at this location: -90 - 12 + 2x1. 5 = -99 dBi. As a result of the installation of the new antenna, we need guaranteed to get at least the second row of the table, in the interval from -90 to -80. Ideally, more than -80, the first line. If we keep the same cable, you need a antenna with KU at least 18dBi, better 20dBi (don't forget about the weather and the natural "swimming" signal). The output will be if not the first row, then close to it: -99 + 20 — 2x1. 5 = -82 dBi. The result can be considered very good: provided that the indicators RSRQ and RSRP SINR vary in proportion to (and usually do), we "pull out" of the connectome at least 80% of what he can give. Assume that the maximum supported rate on the BS 30 Mbit/s. Received 30 * 0,8 = 24 Mbps. We are interested in two parameters: RSSI (Received Signal Strength Indication) level of the received modem signal. This is the main "honest" indicator of the level. Is measured on a logarithmic scale in dBm. Other parameters from tables such as RSCP, RSRQ, RSRP, CQI — are service. They usually correlate with RSSI, so they shouldn't be ignored. The second, not less important parameter, especially in dense areas – the ratio signal/noise. Denoted for 3G: ECIO (Ec/Io) or Ec/No; 4G: SINR (Signal to Interference / Noise Ratio) or CINR (Carrier to Interference / Noise Ratio). Is measured on a logarithmic scale in dB. Ec/Io is a measure of signal/noise, but very tricky. Compared to conventional SINR indicator (which is used in LTE) of Ec/Io deducted natural noise. Indicator Ec/Io = 0 dB is the level when in addition to natural thermal noise nothing. Any interference of artificial origin reduce Ec/Io. (from their own neighboring BS in the first place, this effect operators is called "cell respiration" - on the border between the cells preventing the signal level from another cell of the same operator becomes significant, and in spite of a strong total signal prevent set high speed) As Ec/Io, Eb/No, SINR, and so this is all adaptive indicators. Because the link can't work with poor Ec/Io (Eb/No), then the weak signal to improve Ec/Io of BS and the subscriber agree to lower the bandwidth: used less than RB (resource blocks) and a lower modulation scheme (QAM64 - QAM16 - QAM8 - QPSK - BPSK) Therefore, by itself, the Ec/Io does not show good signal or bad (in pulsometro this figure is NOT used). It shows the contribution of artificial noise (reflection, alien sector, industrial noise) Need to watch it paired with RSCP. RCSP of these 3 the most objective indicator is the amount of energy per 1 resource block (in LTE) or channel (in 3G) is the Received Signal Code Power (RSCP). RSCP that is used to parcometre. Also it is based on the RSCP telephone/modem decides which of the cells to connect.
