Abstract:
A hemisphere dielectric resonator pattern reconfigurable antenna (DRA) is proposed in this paper. The proposed antenna element can operate in four states (SI~SIV) and correspondingly reconfigures its patterns in four directions. A thinning linear array by non-uniform spacing with the element is constructed to scan its main beam from θ=-77o to 77o in E-plane with 3-dB beam coverage from θ=-90o to 90o by changing two states and progressive phases.
