Hi all,

I wanted to feed the dipole patch antenna with the wave port(the figure of the antenna is below), but I don't know how to do that.

I know how to feed it with lumped port. However, I'm willing to know the input impedance of the proposed antenna.

Thanks all

(I have hiden the substrate, and GND doesn't exist)

I would suggest that you add the proposed feed structures to the antenna.

You can use two semi-rigid coaxial cables with their outer shields soldered together. The pins of the cables would need to be excited 180 degree out of phase. See [1] and [2], especially the figure in slide 16 of [1]. I would suggest that you add such a structure to your model and then excite it using two wave-port excitations at the end of each coaxial cable.

Thanks a lot jeeudr!
I have also seen your reply in https://www.edaboard.com/threads/286268/
The suggestion here is more helpful, but it seems a bit difficult for me to realize the feed structure. I will try to do that!
Thanks again~
