Abstract

Antenna systems are provided including a chassi and first and second radiating elements coupled to the chassi. The first radiating element is configured to amplify excitation of the chassi and the second radiating element is configured to reduce excitation of the chassi so as to reduce mutual coupling in the antenna system. Related co-located antennas and methods of controlling mutual coupling are also provided.
