Abstract

The purpose of this paper is evaluation of radiation pattern interaction and input impedance coupling between two adjacent ground station antennas in different frequency bands. Thus the antennas were simulated in different distances. Then a reliable relative distance for proper radiation performance, with acceptable characteristics degradation (in communication link), was defined. NEC-pro Software was used as the solution code for the antenna structure modeling
