Antenna Receive Mode

I want to simulate a Vivaldi array with 2 elements in receive mode. The only way to do this, as far as I can tell, is to use the receiving antenna far field request. However, in the user manual it states that no coupling is taken into account and that the antenna is seen as ideal with this request. This is unfortunate since I do want to take mutual coupling between the antennas into account - that is the main goal of this array simulation, to determine the coupling effects. Is there another way to simulate antennas in receive mode that takes coupling into account?

    Hi Eliz


    Correct, equivalent sources do not take coupling to nearby geometry into account.

     

    Any antenna can be used in receive mode by just adding a port and a load, typically 50 Ohm to the port. Then you will look at the received power in the load in POSTFEKO.

    Usually the source is then a plane wave or maybe another antenna that contains a source.
