A new synthesis technique is developed for a phased array antenna to radiate optimum field patterns in its near- or far-zone. This technique employs a domain transformation of field basis functions using array elements' radiations, and may overcome the over-coverage problems arising from the broad patterns of basis functions. The technique accelerates the synthesis procedure because the new, transformed...
This paper presents an efficient approach to synthesize the near-field pattern of an antenna array for RFID applications. This approach utilizes a global basis set to represent the excitation amplitude of the array with an additional phase impression to generate focused spot beam in the near zone, which is combined with a standard synthesis algorithm of MLSE to generate a contoured pattern. Numerical...
An efficient procedure, based on a discrete Fourier transform (DFT) expansion of planar array distributions, is described for synthesizing contoured beams in satellite antenna applications. The DFT provides a global basis set that spans over the entire array, and thus produces highly directional beam patterns to serve as corresponding local basis functions for representing the desired far zone radiation...
