Abstract
A port isolator for an antenna having a horizontal polarization input port and a vertical polarization input port includes a first signal coupler, a signal adjuster, and a second signal coupler. The first signal coupler is configured to sample a signal received on one of the input ports of the antenna. The signal adjuster is electrically coupled to the first signal coupler. The second signal coupler is electrically coupled to the signal adjuster and the other one of the input ports of the antenna. The signal adjuster is configured to adjust a phase and an amplitude of the sampled signal based on a leakage power and a leakage phase of a leakage signal from the input port receiving the signal to the other input port. The adjusted sampled signal substantially cancels out the leakage power and leakage phase from the input port receiving the signal to the other input port.
