Abstract :
We proposed a novel beam switching antenna system which is composed of multiple microstrip comb-line antennas with different beam directions in the perpendicular plane to the feeding line. We applied aperture Taylor distribution in perpendicular plane to the feeding line of microstrip comb-line antenna to reduce sidelobe level. All dimensions of radiating elements are optimized in this design. Sidelobe levels for various beam tilting angles are evaluated in this paper.
