Aperture Coupled Microstrip Slot Antenna

A microstrip-fed aperture coupled microstrip antenna was designed by Rao et. al. [1].  A variant of this antenna was implemented in FEKO for the following specifications: 5.5 GHz centre frequency 50 Ω input impedance Substrate, ε = 3.2, height = … Read More

Proximity Coupled Circular Patch Antenna

An example of how a proximity coupled circular patch antenna may be simulated with FEKO. Davidovitz [1] and Alonso-Monferer [2] independently analysed a circular microstrip patch antenna with proximity coupling. A simple FEKO simulation was constructed and compared with their … Read More

Shielding Effectiveness of Metallic Enclosure

A metallic enclosure containing a number of apertures is modeled in FEKO to determine its shielding effectiveness As wireless communication increases in popularity the shielding of radiation sensitive devices / circuitry becomes more and more important.  A simple shielding technique … Read More
