Manipulating antenna radiation patterns with angle holography

We introduce a new method of integrating holography into microwave antennas. Interference patterns of a reference wave with a desired wave can be represented using tilted radiating elements. By either feeding the elements directly or with an incident wave excitation, the Angle Holography array can then reproduce the desired output wave. The proposed design aims to provide features current holographic systems do not posses such as frequency scalability, simplicity in feeding, and ease of design and fabrication. Two 1D array designs are discussed, one for beam steering and the other for Fresnel zone focusing. Through full wave simulations, preliminary results validate the proposed idea and designs.
