I think this patch would be more interesting...

,,, welcome yurik82...!!! ,,, why don't you post some pictures...??? I think elliptical patches are harder to build for DIY...!!!

In the proposed antenna, however, the slot lengths ( E1-E4 ) play important roles in controlling not only the bandwidth but also the port isolation. It can be seen that when the slot length decreases, the lower resonant frequency increases and leads to bandwidth deterioration, due to the fact that the inductance of the slot is reduced as the slot length decreases. ,,,and this it"s the simulation...

A compact dual-polarized double E-shaped patch antenna(ESPA) with high isolation for pico base station applications is presented in this communication. The proposed antenna employs a stacked configuration composed of two layers of substrate. Two modified E-shaped patches are printed orthogonally on both sides of the upper substrate. Two probes are used to excite the E -shaped patches, and each probe is connected to one patch separately. A circular patch is printed on the lower substrate to broaden the impedance bandwidth. Both simulated and measured results show that the proposed antenna has a port isolation higher than 30 dB over the frequency band of 2.5 GHz – 2.7 GHz, while the return loss is less than -15dB within the band. Moreover, stable radiation pattern with a peak gain of 6.8 dBi – 7.4 dBi is obtained within the band. ,,,MADE BY Yanshan Gou, Shiwen Yang, Quanjiang Zhu, and Zaiping Nie

I'm sorry, I don't have this drawing in the original, I made an approximate measurement...!!! ,,, ask "acri" where he found this drawing ... !!!

Figure 1(a) shows the conventional patch with a feeding line. Next, the radiating patch is rotated 45◦ clockwise from the initial design, as shown in Figure 1(b). Finally, as shown in Figure 1(c), the chamfering is applied to the antenna on the left and right side as well as at the upper part of the radiating patch (labeled C0 and C1). An inset feed was applied to feed the radiating patch. The antenna design simply allows a further reduction in size of the radiating patch with the inclusion of the chamfering. The coordinate system is inserted in all related figures in this paper to facilitate a clear view of the design structures and radiation pattern.

,,, you mean you say .... thank you very much, admin...??!! ,,, without Russian language, please ... !!!

,,, this is the promise made previously....

This is an achievement of my Mexican friend, Julungas...

,,, put the dimensions ... !!! and this is Eric's picture...

,,,yes...!!

,,,the feedpoint never in the center...!!!!

,,bejo...go to the Modeling>Curves>Poligon>Create Poligon triunghiular>Extrude Curves with Thickness"g">>>>and so...!!!

,,,thanks....!!!

,,,hi buddy..!!! I didn't make much progress with this antenna, but I will be ready soon..!!! I try to see if the lids from the liver pate boxes can be used...!!!

,,, in X-polarization, they are lost, approx. 3 ... 5 db ,,, but you could try this option too.. !!!???

Bravo,,,!!!... and how it works .. ???

,,,Bejo, look what they did....!!!

,,,not yet...!!! ,,, but soon .. !!!

,,, the thickness of the material does not influence too much the frequency, the dimensions must be changed ... !!!!

„, these are the results with 0.2mm metal sheet...

This project want to cover all of the cell phone bands, WiFi and Bluetooth up to 6 GHz as well as the new UWB band from 5 GHz to 10 GHz with just one antenna installation.He did not want to maintain a dozen different antennas with multiple ranges and tuning; just one ultra wideband antenna. https://www.rtl-sdr.com/constructing-a-3d-printed-wideband-900-mhz-to-11-ghz-antenna/

,,,okay buddy,I will try,,,but tell me this antenna is on the PCB ... ??

,,,okay,I will try to do a cst modeling for you...!!!
