An Autonomously Adaptable Self-Structuring Patch Antenna
IntroductionThe patch antenna (PA) is widely used in communications and radar systems. Its primary benefits over other types of antennas are that it is conformal, and can thus be placed onto the surfaces of aircraft and land vehicles, that it is polarization diverse (can be configured for multiple polarizations), and that it is simple to construct....
