L-Probe Fed Conformal Patch

A spherically conformal patch antenna is modeled in FEKO to determine its impedance match and radiation patterns Certain applications require antennas to conform to a specific shape or surface. Conforming an antenna to a certain shape affects its performance.  These … Read More

Time Analysis of UWB Antennas

An elliptical patch antenna is simulated to illustrate how FEKO can be applied to investigate time domain characteristics of UWB antennas including the fidelity, a measure of how similar the radiated waveform is to the excitation signal. Ultra-wideband (UWB) antennas … Read More

Log Periodic Dipole Array

A log-periodic dipole array is modeled in FEKO to determine input impedance and radiation patterns Log-periodic dipole arrays (LPDAs) are wideband structures having a geometry such that its impedance and radiation characteristics vary periodically with the logarithm of frequency. This … Read More

Ku-Band Waveguide Filter

A Ku-band waveguide filter is modelled in FEKO to determine its frequency response Waveguide transmission lines are used in communications systems to feed horn or slotted waveguide antennas.  A filter is usually required to remove unwanted signal content and realising … Read More
