Radiation Hazard Investigation for Multiple Simultaneous Transmitters

Introduction Radiation hazards have to be within standardised limits for many different hazard applications, e.g. human safety (HERP), fuel (HERF) and ordnance (HERO). Most radiation safety standards define maximum limits for field strength in frequency bands and form an equivalent … Read More

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
