In this paper, a new method is proposed for calibrating a planar array of general geometry with respect to errors in location, phase and gain, even when all errors are present simultaneously (global calibration). The method requires the use of three pilot sources, which operate one at a time and from at least two different azimuth angles. Since the sources need not operate simultaneously, one o...

Linear and planar antenna arrays are synthesized to have maximum directivity for a specified sidelobe level. The directivity is maximized subject to a given SLL. The beamwidth and the zeros of array factor are studied as well as the directivity. Maximum directivity-arrays are compared through some examples with super-directive, uniform, Dolph-Chebyshev and Riblet-Chebychev arrays to find a comp...
