Shunt Coupled Spiral Inductor

A spiral inductor on a substrate is simulated in a shunt configuration and its S-parameters extracted. This article presents FEKO simulations that are representative of RF components that are constructed on a dielectric.  The model that is simulated here is … 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

Intelligent Design with Characteristic Mode Analysis

This white paper illustrate the benefits of CMA for antenna design and integration. The theory of Characteristic Mode Analysis (CMA) is a well-known method originally proposed by Garbacz [1] and later refined by Harrington and Mautz [2] that allows for … 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

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
