Abstract
Baluns and antenna devices that achieve improved antenna isolation for simultaneous transmit and receive (STAR) antennas are provided. A tunable balun can be used to compensate for amplitude imbalances in a multi-antenna radio, and/or an antenna agnostic feed network can be used to improve isolation in a single antenna radio. The balun can be integrated directly into the antenna. The balun can control the amplitude of each signal to ensure they are equal, resulting in greater transmitter interference cancellation.
