Abstract
A beam steering (up to 36 degrees) high gain (20.5 dBi) Leaky-Wave Antenna (LWA) is presented at 26 GHz for enhanced data rate in millimeter wave (mm-wave) 5G system in dynamic environments. A low loss (<0.1 dB) tunable High Impedance Surface (HIS), acting as phase shifting surface, is employed for the antenna's beam reconfiguration. The HIS is tuned electro-mechanically, using an amplified version of Piezo-Electric Actuator (PEA) that produced 430 mu m displacement variation. The proposed LWA exhibited fast (m-sec) and continuous beam steering and was employed in a high throughput mm-wave 5G system testbed for both line-of-sight (LOS) and non-line-of-sight (NLOS) links.
