Two-Port Probe-Fed Circular Antenna

A two-port probe-fed circular microstrip antenna is simulated as an example. This example presents the computation of the S-parameters for a two-port probe-fed circular microstrip antenna. The antenna was orginally analysed in [1], allowing simple validation of the FEKO results. … Read More
