,,,,for which this MiMo antenna can cover the frequency band 2.1-2.6 GHz ... ???

Single band IEEE 802.11 a/n standard High gain patch antenna Frequency (MHz) : 5150-5825 Peak Gain (dBi) : 10.0 VSWR : 2.0 : 1 Dimension (mm) : 76 x 72 x 3.8 Connector : IPEX MHF I Cable Length (mm) : 50 (customized) It seems to work well on the 5.6 GHz frequency.

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 theory of these antennas from the electrodynamic point of view is very difficult. At the moment, the parameters of such devices are selected empirically with the help of software systems electrodynamic simulation such as CST Microwave Studio... And here's one of my older projects.... By pasting a line of triangular adaptation can adjust impedance across the frequency range.

The BDM-2 is a wave channel with crack initiation, and delay line is made of sequentially installed disk elements. Compared to classic antenna BDM new directed antenna BDM-2 is: More gain; Improved radiation pattern; More stable operating parameters; Greater reliability; Superior mechanical characteristics.

Hello everyone.Here are proven horns for offsets at 5.4 Ghz offset 60cm . horn5,4ghz.cst

Anyway, I like pyramidal horns, better, because they are easier to build....!!! ,,,and some constructive details... ,,, if the dimensions of the pyramidal cone are reduced by half(240/2x175/2x290/2), these results are obtained...

,,,,from zero13wireless.net...!!! Here it is the measurements of the a box-can with a horn that can put it together: Vibrator=65 mm diameter core placed 8.5 mm above reflector (bottom of box-can) Director1 =58 mm diameter, placed 2.2 mm above the vibrator Director2 = 38 mm of diameter, placed to 65 mm on the reflector (bottom of the box-can) Director3 =70 mm diameter, placed 137 mm above the reflector (bottom of the box-can) All the elements traversed by rod of 3 mm of diameter including the reflector. Horn Measurements: Base opening 190 mm (equal to container width) Horn opening 307 mm Perpendicular height of 95 mm The simulation is made of 0.5 mm thick copper.

,,,okay,thank you...!!! ,,,but you see, I addressed this topic a few years ago...!!!

,,,yes...!!!

Is a Russian patch-antenna for its positioning in the focus of a parabola offset... Antenna is broadband (2.3-2.7GHz) Bester Antenna on the offset dish It has a elliptical polarization antenna.

,,Heinkel,you are from Spain...??? ,,,it means you met zero13 wireless.net...!!!

Okay Clanon, I'll try to do this too...!!! Yes, that's it.... RondCone.cst

,,,another version with different dimensions...

It was interesting to design a small and lightweight antenna from available materials for FPV. After looking at what is available in household stores, I decided to stop at zinc/brass for the antenna elements and a canister cover as a radom. And so everything is in order - as it seemed to me, a lid from paint cans / mounting foam / air fresheners is perfect for radom. Its diameter is 77 mm external and 84 mm internal. Height from 12 to 40 mm. Material-polypropylene. Based on this, the dimensions of the entire structure were selected. you will need brass / galvanized 0.25 mm thick, brass tube diameter 4 mm external (wall thickness 0.25 mm), screw m3 -40 mm. cap nut m3, SMA connector, pipe cutter, metal scissors, drills with a diameter of 1.4 and 3 mm. The reflector is made of sardine cans. General view of the structure and results:

In telecommunications, a collinear antenna array is an array of dipole antennas mounted in such a manner that the corresponding elements of each antenna are parallel and collinear, that is they are located along a common line or axis. Collinear arrays of dipoles are high gain omnidirectional antennas. A dipole has an omnidirectional radiation pattern when in free space and not influenced by any other conductors in that it radiates equal radio power in all azimuthal directions perpendicular to the antenna, with the signal strength dropping to zero on the antenna axis. The purpose of stacking multiple dipoles in a vertical collinear array is to increase the power radiated in horizontal directions and reduce the power radiated into the sky or down toward the earth, where it is wasted. They radiate vertically polarized radio waves. Theoretically, when stacking idealised lossless dipole antennas in such a fashion, doubling their number will produce double the gain, with an increase of 3.01 dB. In practice, the gain realized will be below this due to imperfect radiation spread and losses.

Yes, it seems like they should be larger in diameter...!!! ,,,now it is 20 mm...

The four-arm helical structure antenna is composed of four helical arms, and the length of each is an integer multiple of a quarter wavelength. The current amplitudes of the feed ends of the four spiral arms are equal, and the phases are sequentially different by 90°. It has a cardioid pattern, a good front-to-rear ratio and excellent wide-beam circular polarization characteristics. It is very suitable for use as a receiving antenna for a satellite positioning system. Parameter: Antenna impedance: 50 ohms Working frequency band: 1.4 ~ 1.68GHz Size: 23mm*78mm*1.6mm Weight: 8.4g Antenna connector: SMA (male)

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

Bottom of a circular metal box can build a simple antenna with an elliptical radiator...

No, I don't think so, but I'll try to do a simulation of what this type of helix is like. What frequency are you interested in??

Go to template based post processing and select far field from there and then go to results and calculate electric field for theta and phi and find the phase difference which actually gives the polarization whether linear, circular or elliptical.
