Near-Chebyshev Pattern for Nonuniformly Spaced Arrays Using Zeros Matching Method

An analytic method is presented to design nonuniformly spaced uniform amplitude antenna arrays (NSUAAs) to have near-Chebyshev radiation pattern. In this method, called zeros matching method (ZMM), the zeros of array factors of NSUAAs are matched with the zeros of the exact-Chebyshev pattern. Some examples are brought to verify the effectiveness of the ZMM approach for both linear and planar NSUAAs.
