Abstract
In this paper, an anti-jamming GPS array antenna with seven antenna elements on the conformal structure is proposed for GPS applications by switching on/off the antenna ports. In this proposed antenna, when the received power is high, the antenna feeds are switched off to create null in the direction of jammer to reduce the jammer effect. This structure composed of seven patch elements where each element placed on special face of the structure. Whatever antennas be more directive, we can create deeper nulls. These specifications introduce this antenna as a good candidate for GPS applications to mitigate the jammer effects.
