Direct Synthesis of Accurate Angular Filtering Patterns using Holographic Leaky-Wave Antennas

We propose a new synthesis technique of angular filtering radiation patterns, using holographic leaky-wave antennas. The synthesis is based on the association of a set of N leaky waves with the response of a passband filter of order N. Compared to previous broad-beam synthesis techniques, the novel method provides accurate angular filtering specifications with demanding restrictions (ripple and rejection levels), and without numerical optimization.
