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

3 жыл бұрын

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.

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.

Good question. Usually thi smethod gives good results. But if it is not working, please check your model. You probably have some issue there. It also happens with me.

That is really good question. CST can simulate electric and magnetic fields radiation from the antenna. To induce voltage you need a source.

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.
