Output Signal from a Patch Antenna

Hello,

 

I have designed a coaxial probe fed microstrip patch antenna and have excited it with a trapezoidal input pulse (using the 'New Time Signal' tab in POSTFEKO). I want to obtain the output signal at a certain distance from the antenna. How can I do that?

 

Thank you in advance.

    You need to add a near field request in CADFEKO and solve the model again. It should be fast since by default Feko stores the solution (.str file).

    Then in POSTFEKO add e.g an empty Cartesian graph and add the near field from the Time Analysis tab to the graph.

     

    Of course the above assumes that you have set in CADFEKO sufficient bandwidth and frequency samples to be able to represent your input signal in the time domain.
