Abstract
An apparatus and method to provide isolation between a first antenna and a second antenna, each of which is located on a ground plane. A slot that is tunable by a variable reactance is located on the ground plane, the slot not being appreciably resonant at the operating frequency of the first antenna and the second antenna. The antennas operate in an orthogonal mode. Varying the slot reactance varies the electrical distance over which the coupling current between the two antennas flows. Increased RF isolation to a desired magnitude results by maintaining the orthogonality at desired bands. The RF isolation can be measured and a departure from the desired magnitude of isolation causes the reactance to be varied to increase the RF isolation back to the desired magnitude. The antennas and the slot are placed at locations on the ground plane of high current density.
