The antenna is not too good,,,, it needs to be rotated the patches, for circular polarization,,,

To adjust the antenna with the 50 ohm coaxial cable, use a shunt as in the figure below

A quad antenna is a type of directional wire radio antenna used on different frequencies . Like a Yagi-Uda antenna ("Yagi"), a quad consists of a driven element and parasitic elements; however in a quad, each of these elements takes the form of a loop of wire, which may be square, round, or some other shape. Below is a simplistic construction of such an antenna in the 2,442GHz band ,,and the simulation...

Remains to be solved Port1 in the future...!!!

How does Port1 look .. ?? Irg, do you know?

Port2 goes, port1 needs to be resolved

How to simulate 2x2 array antenna

Only under that form I have now found pcb simple biquad.cst

Ok, to keep in mind ... !!! But what modem does the 76 ohm impedance at the imput,,,???

Erkin,what"s the state of work with our antenna?

...this antenna it"s with 75 ohms ports...!!!

,,,I will soon post my dimensions as well...!!!

What are some good software tools for antenna... ??? It depends mainly on the geomtery of the structure and the required accuracy of the solution. For example ZELAND IE3D is based on MoM(method of moments) solution of integral equation which has an excellent accuracy for frequency domain analysis. However, the interface of IE3D is not quite suitable to include very fine details on the geomtery of the structure. Thus, if the structue is simple like rectangualr or circular, IE3D would be the best. On the other hand ZELAND Fidelty, is based on FDTD(Finite Difference TimeDomain) analysis. It is based on combination of specific geometeries. It is also mainly suitable for regular shapes like cylinderical DRA as an example. Both MoM and FDTD are not suitable for large antenna structures like reflector antenna or large antenna arrays. Ansoft HFSS and CST have much better interface which enable te user to include very fine details in the geometery of simulated structure. HFSS is based on Finite Element method and CST is based on a method which is similar to FDTD. Both techniques are still suitable for small or moderate objectes compared with the operating wavelength. The advantage of CST is that within on run one can obtain the results on a wide band because it starts in time domain and convert the results to FD via Fourier Transform. Different opetions are found in HFSS, but it is still FD solution. The accuracy of Finite Element is slightly less than the accuracy of MoM. Thus for regular shapes like rectangular patch antenna you may obtain slight difference between HFSS and Zeland IE3D. In this case the result of Zeland IE3D is the more accurate result. However, for complicated geometery, you may find the accuracy od HFSS and CST are much better than IE3D due to the approximations which you have to do in the geometery of the structure. Luckily, the FEKO electromagnetic computational suite provides various computational electromagnetic (CEM) techniques, including MoM, FEM, MLFMM, PO, GO, and UTD , in a single package. At the same time, the FEKO suite is capable of hybrid simulations mixing the CEM codes. Thus, the FEKO suite provides a versatile set of tools, offering time-efficient and accurate solutions for a variety of EM problems. FEKO has two main solvers, one is based on MoM and another based on GTD. The part of FEKO which is based on GTD cannot be replaced by Zeland, HFSS or CST beacuse it is mainly suitable for large strucutures like reflector antennas. In conclusion, a good designer should be able to use different CAD tools with deep understand of limits of their numerical techniques and modeling interface.

That's how it could be ...

,,,and what exactly? But first of all, a picture of a thousand words;;

,,,it must to be found...!!!!

But the difference here is more pronounced..

Policarbonat Rexolite 2000x1050x3 mm=350 rouble ,,, это дорого?

невозможно не быть таковым в России....!!! Требуются ... !!!

вы можете сделать что-то подобное с наклоном ниже ...

Everywhere there's something like that ...!!!! Dielectric Properties of Rexolite® - Outstanding! Rexolite® maintains a Dielectric Constant of 2.53 through 500Ghz with extremely low dissipation factors. Rexolite® is ideal for microwave lenses, microwave circuitry, antennae, coaxial cable connectors, sound transducers, TV satellite dishes & sonar lenses. Other applications for Rexolite® include nondestructive material testing devices, surveillance equipment, radar windows, radomes and missile guidance system housings. One interesting application for Rexolite® are radar lenses which are used in mapping the Earth's surface from fast, high altitude aircraft. Technical Data Sheet... rexolite.pdf

How to screen a box of panel antenna with Rexolite Dielectric Constant(1MHZ-500GHz) = 2,53-2,62 As can be seen from the above images, the VSWR does not change significantly by attaching a Rexolite screen Due to the relatively low dielectric constant and the high frequency range, this material is recommended for shielding the antenna panels.

50 Ohm I'm not working with 75 ohms

what lateral radiation?

Best so,,,, I will do it....!!!!
