GPR propagation simulation and fat dipole antenna design
Two applications of FEKO are reported. The first application is investigating how antennas propagate. reflect, and the difference in transmit and receive signals in various ground media. Results of the ground penetration simulations done in FEKO (MoM- Method of Moment) is compared to Finite …

Numerical Analysis of Helical and Log-periodic Antennas for Short Pulse Applications
… calculated using CST Microwave time-domain and FEKO frequency-domain simulations of the structure. A comprehensive parametric study of the helical antenna is conducted in FEKO followed by a multigoal optimized design of an L band helical antenna to minimize pulse dispersion, size, and input …

Investigation of a Novel Dual Band Microstrip/Waveguide Hybrid Antenna Element
… HFSS and Method of Moments based software, FEKO were employed to perform parametric studies of the proposed dual band antenna. The antenna was not tested physically. Therefore, in most cases, both HFSS and FEKO were employed to corroborate the simulation results.

Ultra-wideband miniaturized microstrip patch antennas for wireless communications: design guidelines and modeling
… extensively investigated with simulations using FEKO. A set of simple design guidelines is proposed to provide approximate rules that result in optimum "first-pass" designs of probe-fed, miniaturized, low profile, microstrip UWB antennas using different bandwidth-enhancement techniques to satisfy …

Design and implementation of a dual polarised L-band parabolic dish antenna for NeXtRAD
… have been simulated using a combination of FEKO v7 and CST 2014 to compare and verify the designs and simulations. Due to manufacturing limitations, the optimal antenna design could not be manufactured and, as a result, compromises had to be made in order for an antenna prototype to be …

Design and feasibility evaluation of low-cost 3D printing of Horn Antennas
… using the microwave simulation package FEKO. The X-band horn has been fabricated using an FDM-based 3D printer and metallised using conductive paint. Ku-band pyramidal and conical horns have also been designed and 3D printed using the same method and have been metallised using both …

Design of an HF transmit antenna for bistatic ionospheric soundings in Antarctica
… substrate ground plane was modelled for use in FEKO simulations. Several antennas were investigated through an iterative design process and a three-element rectangular loop Yagi-Uda was chosen for final consideration. This was because it not only performed the best but was the most compact …

Investigation into the design of ultra-wideband (UWB) and multi-band antennas
… antennas have been empirically optimised using Feko® and the theoretical and experimental results are provided, in the point of view of reflection coefficient, radiation characteristics, phase response of antenna transfer function and time domain response. For better suiting the compact and …

Collaborative control of wave glider platforms - Local Communication and Sea State Estimation
… using the computational electromagnetic package FEKO. It revealed that, at the frequency of operation, which was 868 MHz, seawater reacted as a lossy conductor and reflected the signal upward, with negligible power penetrating the surface of the ocean. The subsequent study reviewed the …

Simulation of Simultaneously Negative Medium Metamaterials
… measurements. The full-wave simulation tools FEKO that employs the Method of Moments (MoM) is used in the two ways of estimating the negative refractive index of the medium.

Novel techniques for improved indoor positioning and localization using HF RFID
… by using a well known antenna design package “FEKO”. All the key analyses, equivalent circuits, antenna models and computational results for the proposed antennas and algorithms have been verified using extensive experimental campaigns to demonstrate the practical usefulness of the proposed …
