Summary :

The reduction of coupling between two wire antennas operating at different frequencies on an infinite ground plane is considered. An impedance loaded slot is introduced between the two antennas. A coupling coefficient and a transmission coefficient are used to evaluate the coupling behavior. It is found that by an appropriate choice of the slot length, location and load impedance the coupling coefficient can be reduced significantly. The problem is analyzed by the method of moments. Port parameters are used to relate a feed port, load ports on the two wire antennas and a load port on the slot. In so doing, a large amount of computation time is saved in calculating the antenna characteristics for various loads on the slot.
