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

Dielectric Resonator Waveguide Filter

An evanescent-mode waveguide filter consisting of two parallel cutoff waveguide paths with dielectrics is modeled in FEKO and compared with results from the open literature. The authors of [1] describe an evanescent-mode waveguide filter consisting of two parallel cut-off waveguide paths … Read More

Y-Patch Antenna

A two-port y-patch antenna is modeled in FEKO to determine isolation between ports and radiation patterns of the antenna Communications technology is constantly aiming to achieve higher signal-to-noise ratios (SNRs) and especially for portable devices a compact design is required. … Read More

Naval Radar Analysis with UTD

Read about how the UTD is used to analyse radar antenna placement on a frigate. Overview Problem setup: Consider a frigate of length 120 m An antenna (e.g. for radar purposes) is located in front of the forward mast, to … Read More
