Rectangular Patch Antenna Residing in a Cavity

A description of how infinite plane Green’s functions and the MoM Surface Equivalence Principle (SEP) may be used to simulate a rectangular patch antenna residing in a cavity. This example considers a rectangular patch antenna residing in a cavity. The … Read More

Two-port probe-fed circular antenna model

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


Microstrip Filter Optimisation Using Masks

This page describes the optimisation of a microstrip line filter with the use of masks. Specified filter characteristics are realised. Introduction In this article, the FEKO optimisation mask feature will be used to optimise the response of a microstrip filter. … Read More
