Mutual coupling between short-circuited microstrip antennas
Abstract
A method has been previously developed for the computations of mutual coupling between the usual rectangular printed antennas. In the letter the short-circuited antennas with three magnetic walls and an electric wall are investigated. Using the cavity model with hybrid boundary conditions (magnetic wall and electric wall) and the equivalence theorem, the problem is reduced to the interactions of two U-shaped magnetic currents. Theory and experiment are in very good agreement.
