  1. The only major drawback of the TL-MR3020 is the lack of an external antenna connector, this however can be easily hacked in a couple of simple steps and takes less than 15 minutes. Option A: If you want to use a Pigtail: Solder the center of RG-174 (or the like) coax cable to the left pad (connected to C43 - see Image) and the braid/shield of the coax to the right strip (GND). Option B: If you want to use a PCB Edge RP-SMA connector: Solder the center pin (round) to the left pad (connected to C43 - see Image) and the right pin of the connector to the right pad (GND). There have been reports of EM related damage to MR3020 routers that have been hacked the way shown below. It seems that the cut off capacitors after J4 were put there for EM protection rather than matching the antenna. Please follow the method shown above to have proper EM protection for your router's external antenna. The following images are only left as a reference for now
  2. Hope to see you via EME(Earth-Moon-Earth) on 23 cm Two-way radio communication on VHF ,UHF,SHF and above using the Moon as a passive signal reflector. Commonly referred to as “moonbounce”.
  3. Powerful broadband antenna 3G/4G/2G/Wi-Fi with support for MIMO 2x2. Strengthening 15-17,5 dBi.It is recommended to use complete with universal modems Huawei Е392,E3276(M150-1) and conventional 2G,3G and 4G modems. Panel antenna MIMO 2x2 AGATA is intended for use in complete equipment of wireless data transmission systems standards: 2G(EDGE, GPRS frequencies GSM1800) 3G (UMTS 2100) 4G (WIMAX,LTE1800, LTE2600) WI-FI (IEEE 802.11 b, g, n) in other systems the range of 1700-2700 MHz. AGATA MIMO 2x2 antenna is highly directional and ideal for use in communication systems "point to point" and "point-multipoint". Antenna is a structure of two spaced in-phase arrays with orthogonal polarizations.
  4. Waveguide slot antennas are a type of microwave antenna that use a hollow metal tube, called a waveguide, to transmit and receive electromagnetic waves. They have slots cut along the length of the waveguide, which act as radiating elements. Waveguide slot antennas have some advantages over other types of antennas, such as high efficiency, low loss, and wide bandwidth. Single Sided 8 Slots Waweguide...41x20x360mm....
  5. 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
  6. The 4G LTE MiMO 2x2 Tsar-Pushka VARIUS antenna differs significantly from conventional ribbed-rod "pushka" antennas in its wider frequency band. While conventional antenna guns can only be designed and manufactured for a single frequency band, the Tsar Cannon Varius antenna model works perfectly in the 800 MHz band from 1700 MHz to 2550 MHz. The Tsar Cannon antenna can be used on the following bands: Band 1 (1800 MHz) Band 3 (2100 MHz) Band 40 (2300 MHz) Wi-Fi 2.4 (2400-2500 MHz) The antenna has excellent cross-polarization isolation, which allows the MiMO 2x2 technology to operate as stably as possible. Maximum antenna gain of 11-14 dBi The Tsar Cannon antenna has a pronounced radiation pattern. The antenna can also be used in the 2500-2700 MHz band (Band 7, Band 38), but the gain will be low and the SWR will be high. We recommend using this antenna in these bands only in extreme cases when there are no other options available.
  7. If your SINR is quite decent,you can use a small 0.55 dish with an irradiator, as the signal strength allows. As for the speed instability, it largely depends on the provider and the load on the base station. The more users connected to the tower, the slower the speed.
  8. Yes, but you'll have to wait....!!!
  9. ,,,okay bro...!!!
  10. ,,,and yet you still haven't told me what you really want...!!!
  11. I will try to satisfy your desire.....!!! ,,,you want an antenna that works on 1800 MHz and 2100 MHz...???
  12. ,,,post in English..!!!! ,,,and here in this post you will find what interests you...!!!
  13. ,,,hi buddy...!!! Search here and you will find what interests you....
  14. Radiation patterns and gain measurements on 1.0, 1.5, and 2.0 lambda backfire Yagi antennas are given. The backfire antenna was tested for two dipole feed locations, and variations in the diameters of the two planar reflectors forming the backfire cavity. The optimum dimensions of the three test antennas are tabulated. The frequency bandwidth of the backfire antenna is limited to several percent due to impedance matching. The backfire antenna should find application in broadside arrays where conventional endfire antennas are presently used. 19680012807.pdf
  15. Yes, I think it's a good idea, but there are problems with impedance matching....!!! ,,,maybe a circular parasitic patch should be added after the radiator...!!!
  16. The antenna is interesting but it still needs work, it doesn't have a large bandwidth,,,only 1,8----2,2 GHz
  17. ,,, type of antenna,not very easy to produce , but with good results in circular polarization. Between the patch and irradiated put plate of polystyrene or polyurethane...
  18. Antennas are essential wherever wireless communication required. They are the indispensable link between the contained signal and the “ether”. CST provides a variety of tools for each stage of the antenna design flow to study and improve your design. Antennas are used in a vast variety of applications, and thus take come in a vast variety of form factors and radiation mechanisms. The range of simulation methods in CST MWS allows the engineer to choose the best technique for each application. The transient solver could be best for wideband or planar antennas, the frequency domain solver may be more suitable for electrically small antennas, while the integral equation solver can efficiently simulate electrically large or wire antennas. Antennas never operate in isolation, but are attached to a feed network. CST DESIGN STUDIO™ (CST DS) allows the hybrid co-simulation of the effect of an attached circuit on the antenna performance. Installation of an antenna in a device or on a platform makes its analysis even more complex. The System Assembly and Modelling framework in CST DS allows the user to set up coupled simulations which can combine different solvers automatically by making use of field sources. Finally, powerful automated post-processing allows you to extract every magnitude of interest for an antenna designer – nearfield plots, SAR, phase center, directivity or farfield gain for single antennas or arrays - and to process those data further for use in parameter sweeps or optimizations in order to improve the performance of your design.

  19. ,,,double-biquad I don't think it's quite right, why don't you try a batwing antenna....???!!!
  20. Clanon, how do you go about attaching images like that...??? VNA...???
  21. ,,,no, but the interior is built according to the AppCAD program...!!!
  22. ,,,a mini-antenna on PCB...and UWB...!!!
  23. ,,,,with such a bandwidth (1800-2100 MHz), only the Batwing antenna is suitable....!!!
