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

Shielding Effectiveness of a Finite Conductivity Metallic Sphere

An example of how FEKO may be used to compute EMC shielding factors. Problem Description EMC engineers often design a shielding environment for circuitry or people and have to estimate the shielding effectiveness of the structure before producing a prototype.  … Read More

The Effect of Carbon Fibre Body Panels on Aircraft RCS

A simple case study at 50MHz to demonstrate the effect on aircraft RCS of using carbon fibre body panels, rather than metallic body panels. Problem Specification: Compute the monostatic RCS of an F5 fighter aircraft. Demonstrate the differences in RCS … 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
