Abstract
- In this work, a novel multi-feed synthesis for holographic leaky-wave (LW) antennas is presented that considers the angular dependence of each pixel structure. This approach of combining multiple single-beam holograms minimizes the impedance error w.r.t. each individual impedance hologram. A multi-feed antenna with two feeding points at 20GHz is fabricated and measured using this new design methodology. The simulation and measurement results show a good agreement. The fabricated LW antenna has a gain of 21.7 dBi and 22.1 dBi and a side lobe level (SLL) of 9.0 dB and 9.6 dB for both feeds.<br />acceptedVersion
