Abstract
An antenna array comprises two or more antenna elements. Each of the two or more antenna elements is configured to scan within a field of view. Each of the two or more antenna elements is further configured to transmit or receive a signal. The antenna array also comprises a metamaterial lens coupled to the two or more antenna elements. The metamaterial lens is configured to distribute the signal according to a sinc-like distribution over an aperture of the antenna array.

An antenna array comprising:
- two or more antenna elements, each of the two or more antenna elements configured to scan within a field of view, each of the two or more antenna elements further configured to transmit or receive a signal;
- and
- a metamaterial lens coupled to the two or more antenna elements, the metamaterial lens configured to distribute the signal according to a sinc-like distribution over an aperture of the antenna array,
- wherein the sinc-like distribution comprises a sin(x)/x linear distribution.
