PCB UWB antenna Antrad-11 0.6–8.0 GHz UWB highly directional PCB antenna Antrad-11 (RVS-A2) can be used in radar, radio monitoring and radio communication systems operating in 0.6-8.0 GHz frequency bands. Can be used as the measuring antenna. Gain up to 13 dBi (fr.= 3 GHz) Impedance 50 Ohm VSWR not more than 2.5:1 Antenna size 325 х 200 х 1.5 mm Connector SMA (male/female) Material FR4 an attempt of mine...

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.

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...!!!

,,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...

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

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??

4G antenna BDM-2 is a wave channel with crack initiation, and the delay line is made of sequentially installed disk elements. Compared to the classical antenna BDM , new directional antenna BDM-2 is: More gain; Improved radiation pattern; More stable operating parameters; Greater reliability; Superior mechanical characteristics. Due to the small weight, a small sail and streamlined shapes, the antenna BDM-2 can be used in almost any climatic conditions. And corrosion-resistant materials of the antenna will ensure a long maintenance-free operation even in the marine climate.

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.
