Abstract :
The purpose of this paper is to offer new performances to the base station antennas. We propose a new switched beam antenna array based on the 5 times 8 novel Butler matrix topology and providing a cosecant squared elevation pattern. In this paper, the implementation of the beamforming network and the cosecant squared feeding lines at 42 GHz are detailed and some results are presented. The antenna has been fabricated to validate our simulations and the measure process is in progress.
