An Eight-Port Planar Antenna for 3-D Beam Steering

An eight-port planar leaky-wave antenna (LWA) is proposed. This antenna has the capability of beam steering at an elevation angle by changing the frequency at eight azimuth angles. The antenna is planar and has an array of ring slots embedded in a microstrip parallel plate waveguide. We investigate the simulation and experimental results. The measured results have good agreement with the simulation and confirmed the leaky-wave (LW) concept. The proposed antenna yields an attractive, simple, and cost-effective beam scanning over the 3-D space.
