Geodesic H-Plane Horn Antennas

open access: yesIEEE Transactions on Antennas and Propagation, 2023
This article describes a detailed procedure that allows for a time-efficient design of fully metallic geodesic H -plane horn antennas using an in-house ray-tracing method together with an optimization algorithm. With all the propagation in the air, geodesic H -plane horn antennas are low-loss and highly efficient.

Multimode and Multiband Microstrip Antennas [PDF]

open access: yes, 2007
This thesis describes original work on the broadband and multiband matching of microstrip patch antennas. Microstrip patch antennas suffer from many constraints on their performance. One major restriction is their narrow impedance bandwidth.
