Abstract :
A Single-Layered Radial Line Slot Antenna (CL-RLSA) is a efficient planar array antenna for receiving direct broadcast from a satellite(DBS). By arranging the angle and modifying the width and length of slots, this paper proposes a new optimizing single-layered RSLA which can suppress grating lobes, ameliorate return loss and increase the gain. And the article uses a low dielectric constant material, relative permittivity of 1.06. The results of experiment demonstrate the validity of the optimization.
