Design Recommendations for Minimal Antenna Mutual Coupling Using Current Optimization

Anja Skrivervik, Hannes Bartle

This work addresses a first attempt at using current density optimization algorithms to gain insight into the relation between maximum achievable gain in a given direction and the mutual coupling to another antenna nearby. The methodology is presented on t ...

Estimating the Mutual Coupling of Microstrip Patch Antennas on Large Platforms Through Ray-Tracing

Anja Skrivervik, German Augusto Ramirez Arroyave, Hannes Bartle

The mutual coupling between antennas is an important parameter in multi-antenna systems that needs to be controlled in order to ensure the performance of all involved components. While full-wave simulations are accurate in estimating the mutual coupling, t ...

Circularly polarized planar antenna with axially symmetric beamwidth reconfigurability

Anja Skrivervik, Ismael Vico Triviño, Hannes Bartle

This contribution presents the design of a compact circularly polarized antenna featuring beamwidth reconfiguration in both the horizontal and vertical planes. The observed radiation patterns in each of the reconfigurable states present axial symmetry and ...

Improving the radiation characteristics of shorted annular ring antennas through symmetric aperture-coupled feeding

Anja Skrivervik, German Augusto Ramirez Arroyave, Hannes Bartle

In this paper, a novel feeding method for shorted annular ring (SAR) antennas is presented. SAR antennas can be designed to not excite surface waves and hence have desirable properties for many applications. The traditional method of feeding a SAR is throu ...
