A Millimeter-Wave Fixed-Frequency Beam-Steering Leaky-Wave Antenna Based on 2-Bit Phase Control

Le résumé fourni par la source

A millimeter-wave fixed-frequency beam-steering leaky-wave antenna (L WA) is presented in this article. The designed LWA adopts an air-filled gap waveguide as transmission structure to reduce the dielectric loss. By changing the bias voltage to control the ON/OFF state of the diodes loaded on the bottom solder pad, the unit can realize four different phase states with$90^{\circ}$intervals and maintain almost consistent radiation strength. Therefore, by controlling the PIN diodes, it is convenient to switch the phase state of the unit, thereby steering the beams to different angles. In addition, the designed antenna is manufactured and measured for verification. The measured results show a stability of the realized gain and a beam-steering range of$115^{\circ}$from backward to forward. The feasibility of this LWA is verified by comparing measured and simulated results.
