Large Antenna Array Modelling – A Helix Antenna Case Study

Modeling very large antenna arrays can be computationally expensive, even with high frequency methods such as the MLFMM. Detailed steps are given to model an arbitrary size array of wire helices using the radiation pattern point source approximation in FEKO. … Read More

y-patch antenna

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

Rectangular Patch Antenna Residing in a Cavity

A description of how infinite plane Green’s functions and the MoM Surface Equivalence Principle (SEP) may be used to simulate a rectangular patch antenna residing in a cavity. This example considers a rectangular patch antenna residing in a cavity. The … Read More

Two-port probe-fed circular antenna model

Two-Port Probe-Fed Circular Antenna

A two-port probe-fed circular microstrip antenna is simulated as an example. This example presents the computation of the S-parameters for a two-port probe-fed circular microstrip antenna. The antenna was orginally analysed in [1], allowing simple validation of the FEKO results. … Read More

Mutual Impedance Between Elements in Dipole Array

The input impedance of dipole elements in a uniform and fractal array is investigated using FEKO. One of the main advantages of array antennas is its beam-forming capabilities and one of the difficulties in designing an array is the feeding … Read More
