ABSTRACT:
A multi-element antenna with sufficiently small return loss and mutual coupling signals to allow the simultaneous transmission of powerful radar signals and the reception of faint target return signals. The microstrip patch antenna has radio frequency absorbing material place between neighboring antenna elements to reduce the mutual coupling leakage signals.
