[@shwanashtii]

Sir how you calculated the dimensions of substrate? substrate x is 80 and y 80?

[@SimulationMaster]

Dear Shawn, Because of the fringing electromagnetic fields I usually take twice the dimensions of the patch antenna as a starting point. It gives reasonable initial results. After that, if Electric field magnitude does not converge toward the edge, you can increase the dimensions. But it will affect your simulation time. So in the end, choosing twice the dimension of the patch is a good compromise.

Excuse me sir. Very good explanation! May I ask you a question? So i have project about lightning location. Let's say I already have an amplifier circuit on LTspice. So I need an input voltage for the amplifier which is it comes from the antenna. Can CST studio simulate EMF field and induced voltage on loop antenna? I am very very bad at this but I really need to finish this project. And sorry for my bad english

[@SimulationMaster]

That is really good question. CST can simulate electric and magnetic fields radiation from the antenna. To induce voltage you need a source. And it is possible by placing source in the simulation and calculate electric field and by dividing it with impedance get a voltage value. But I don't know how to do this :( If you find the answer please let me know

[@dejo5748]

I went through this tutorial myself. It is very well explained but it does not resonate at 2.4 but at 2.35 which seems very odd. No idea what I am doing wrong.

[@SimulationMaster]

There can be several reasons for this: 1. Your boundary conditions are not the same as mine. 2. Your dimensions are different. 3. Your dielectric properties are different. 4. Your simulation setup is different. In the end, it is normal to get a different resonant frequency. You must optimize your structure by changing the dimensions of the antenna.

sir thats really nice video. i want to ask that your feed line and patch are not merged as there is black horizontal line still visible. is it ok to do this or u have to apply merge command to combine the patch and the feed line

[@SimulationMaster]

that is perfectly fine. CST does not see those lines in simulation. It only sees the meshes. So as long as there is no gap between the parts it is not a problem to not add them up.

[@devayanis5265]

How can we convert gain in dBi to dB??

[@SimulationMaster]

You can not. dBi is a measure of the gain with respect to the isotropic antenna. dB is just a ratio of the voltages or powers. To define antenna gain you must always use dBi.

[@devayanis5265]

@@SimulationMaster thanku..actually in previous CST versions (2016) gain of the simulated antennas used to be represented in dB.. dBi and dB is quite same..when we compare gain of the simulated antenna ( for eg. 3 dB ) with an isotropic antenna having gain 1( 0 dB )..It means simulated antenna can radiate twice when compared to the isotropic (dBi)...or it can radiate twice of input power given (dB)..so it can be the same.. Correct me if I'm wrong

Actually, my results showed the best impedance matching at 2.38 GHz although it was good at 2.4 GHz (reached -15 dB). Would you please help me to figure out the difference?

[@SimulationMaster]

Thank you for your kind message. The reason that the results are different is that you are using a different computer. Although all the settings are the same because of the computational work the results vary. You can use the Optimization tool to further improve the frequency response, but I think that your results are also acceptable.

[@knightben1086]

Very good explination! Even for newbie like me May i ask some qeustions? Is it possible to build patch antenna with operating frequency at 6 GHz? and can we use CST to design the patch antenna in different shape? like triangular shape for example. I’m new here so I actually don’t know much. Thanks a lot

[@SimulationMaster]

Dear Knight, You can design antenna in different frequency by changing patch antenna dimensions. Reducing dimension will increase the frequency. So to make this antenna work at 6 GHz the dimensions must be approximately 2 times smaller. Also you must take into account the feeding path impedance. You can design patch antenna in any given form, but it will change its radiation properties. You must first decide what you want from the antenna. Have a good new year.
