Abstract
Various techniques may be implemented to isolate a receive signal from a transmit signal in an antenna. Signal isolation is desirable because it prevents interference of the signals with one another and minimizes signal noise, which reduces the signal quality. Some of the techniques are symmetry of at least two receive channels with regards to a transmit channel, using differential signals within the antenna, designing receive channel inputs to be orthogonal to a transmit channel, and designing a voltage controlled oscillator to be on the same substrate as the tuning circuitry of the voltage controlled oscillator.
