Abstract

An exact determination of mutual coupling between microstrip patches is presented in this paper. The classical formula for mutual coupling based on multi-port network theory is popular for determining such coupling. However, this formula ignores the impedance mismatching between antenna and its load. In this presentation an accurate formula for the coupling between patch elements is deduced. For impedance matching case the exact formula reduces to the classical formula. The simulation results show that the consideration of impedance mismatching in mutual coupling calculation is very important.
