The design of microstrip dipole arrays including mutual coupling. I Theory. II - Experiment

A design technique which includes mutual coupling is formulated for use with microstrip dipole arrays. The technique is based on iterative solution of a combined design equation and requires as input foreknowledge of the self-impedances and mutual impedances of microstrip dipoles and also the link between the radiating current and the backscattered wave in the feeding line. Procedures for obtaining the input design data for microstrip dipole arrays are then described and the design of a typical array is presented. The design data indicate that mutual coupling is a significant factor which cannot be ignored in the design of small microstrip dipole arrays.
