Controlling coupling in an electrically steerable parasitic array
… passive elements like varactors, avoiding the cost and complexity of devices like phase shifters. Past attempts to design multi-band ESPARs have often superimposed multiple antenna arrays, each scaled for a different frequency band. This often results in large, cluttered, complicated …

Superdirectivity and the Application of Complementary Split Ring Resonators in Directivity Enhancement of Millimeter-Wave Antennas
The use of millimeter wave frequencies is extending to a variety of applications with the development of 5G/6G networks. Due to the small physical size in addition to atmospheric absorption and material losses, millimeter wave antennas suffer from low radiation performance. Motivated by this …
