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.

Abstract translation: 一种在第一天线和第二天线之间提供隔离的装置和方法，每个天线都位于地平面上。 通过可变电抗可调谐的槽位于接地平面上，槽不会在第一天线和第二天线的工作频率处明显地共振。 天线以正交模式工作。 改变时隙电抗会改变两个天线之间的耦合电流流过的电距离。 通过将正交性保持在期望的频带，将RF隔离增加到期望的幅度。 可以测量RF隔离，并且与期望的隔离幅度的偏离导致电抗变化以将RF隔离增加到期望的幅度。 天线和槽被放置在高电流密度的接地平面上的位置。

Abstract: Representative implementations of devices and techniques provide self-interference suppression for a transceiver of a wireless communication system. To minimize interference from a transmit signal appearing on a receive path of the system, a cross-correlation is minimized between the transmit signal and a desired receive signal.
