Large Array Modelling – A Microstrip Case Study

A 25 x 40 element microstrip array is used as a case study of how large antenna arrays may be modelled with the ideal transmitting antenna feature in FEKO. Introduction This case study aims to illustrate how large arrays may … Read More

Dual-Mode Circular Horn Simulation with the MLFMM

A dual-mode circular horn antenna is simulated with the MLFMM and far-fields are extracted. Skobelev et al. [1] described how a dual-mode horn antenna may be manufactured cost effectively with simple modifications to the geometry of the antenna. This page … Read More

Low-Pass Microstrip Filter

A low-pass microstrip filter is analysed in FEKO and the results compared to published media. This article analyses a microstrip low-pass filter that was originally analysed in [1].  The filter was implemented using CADFEKO with the substrate being approximated with … Read More

Coaxial Cable Analysis

Application CADFEKO supports the analysis of arbitrary cable bundles and cable paths. This feature provides the user means of dealing with the problem of irradiation of cables excited by an external field, e.g. a plane wave, but also any other … Read More

Waveguide Applications of FEKO

Introduction The various CEM methods in FEKO make it well suited to the simulation of non-radiating structures. Waveguide circuits are an excellent example of this kind of problem and this application note highlights some of the benchmark simulations of waveguide … Read More

Inverted F Antenna

A symmetric inverted F antenna is modeled in FEKO showing how size reduction is achieved through inductive loading. With recent advances in communication technology physical design constraints of antennas, such as weight and size have become more important and a … Read More

Characteristic Mode Analysis of a Metallic Ring Antenna

Characteristic mode analysis is carried out to give insight into the radiation properties of a metallic ring antenna. The normalised surface current distributions and far field patterns of the first four eigencurrents of a metallic ring antenna based on the … Read More
