Abstract :
We propose a novel beam switching antenna system which is composed of five channels of microstrip comb-line antenna. Each channel has different beam. We applied aperture Taylor distribution in perpendicular plane to feeding line of microstrip comb-line antenna to reduce sidelobe levels. All the radiating elements are optimized in this design. Beam scanning performance is evaluated in this paper.
