Abstract

Dual beam antennas with similar gain and beam-width require multiple antennas fed separately with controlled input phase shifts or a single antenna with a complicated feeding mechanism. To reduce this design complexity, this paper presents an approach that uses one antenna, a simple feeding network and a pair of simple metamaterial-based frequency selective surfaces with uniform rectangular unit cells. Four different surfaces are studied for a 13.6 GHz scalable design fed by one planar source antenna at a time. Results show that different combinations vary the near field phase, which affects beam orientation and gain, and that a single far field beam can be transformed into a dual beam with a split up to 34°. The best design has simulated and measured gain of 14.5 dB for the boresight beam and 11 dB for each of the dual beam.
