Recent progress on the antenna simulation program FEKO

Proceedings of the 1998 South African Symposium on Communications and Signal Processing-COMSIG '98 (Cat. No. 98EX214), 2002
This paper describes recent progress with FEKO, an antenna simulation program. FEKO uses the method of moments (MoM), and also offers users a hybrid MoM/physical optics for suitable electrically large problems. Current work on UTD hybridisation is outlined, as well as work on the pre- and post-processors.

RCS Simulation of Dihedral Corner Reflector Based FEKO

Applied Mechanics and Materials, 2013
CR-InSAR is developing continuously in recent years. It is an important technology in the field of monitoring crustal micro-deformation. Radar cross section of corner reflector is an important work foundation because only radar cross section of artificial corner reflector achieves maximum, it is easier to recognize it from SAR image and increase ...

FEKO/GRASP Simulations of Super-Resolution with a Reflective Metal-Mesh Toraldo Pupil on the 32m Medicina Radio Telescope

2023 Seventeenth International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials), 2023
We are currently carrying out a project devoted to the implementation of super- resolution on single-dish radio telescopes, aimed to obtain an angular resolution better than the classical diffraction limit. A feasible method to achieve this goal consists of using variable transmittance pupils, and specifically the simplest version of these pupils which

Using electromagnetic simulation code FEKO as a numerical laboratory in antenna engineering

2010 14th International Symposium on Antenna Technology and Applied Electromagnetics & the American Electromagnetics Conference, 2010
This paper relates how the FEKO code can be used as a means of performing numerical experiments to answer various “what if” questions that usually arise during antenna design tasks.

Simulation Study About the Radar Cross Section of a Typical Targets Based on FEKO

2021
The radar cross section is an important parameter to characterize radar target characteristics. The fluctuation of the data represents the size and shape of the target. Target RCS depends not only on radar frequency and polarization mode but also on the attitude of target relative to radar.

Design, optimization and simulation of a compact multi-layered microstrip antennas based on LTCC-technology in Feko

2017 Radiation and Scattering of Electromagnetic Waves (RSEMW), 2017
Design and analysis of multilayer stacked-patch antenna with LTCC-technology. It is shown that changing the number of the dielectric layers can increase the working band-width of the antenna compared with single-layer antennas. The use of passive elements in the construction of the antenna (multilayer microstrip antenna) can reduce the change of the ...
