Abstract

A novel technique for continuous electromechanical beam steering is proposed based on Fabry-Perot Leaky-Wave Antennas (LWA). The proposed structure is formed by a Partially Reflective Surface (PRS) placed on top of a High Impedance Surface (HIS) ground plane. The reconfiguration is achieved by means of piezoelectric actuators that tune the reflection phase response of the HIS, thus controlling the pointing angle of the antenna's radiation beam for a fixed frequency. The actuators are placed below the ground plane, producing a change in the cavity distance between the ground and the AMC array. The antenna is designed to operate at around 55GHz. Full-wave simulations have been carried out in 3D electromagnetic simulation software (CST Microwave StudioTM) demonstrating beam configuration with continuous scanning from 15° to 50°.
