Tunable inter-antenna isolation

摘要

A method and system performs antenna tuning to minimize interference affecting signal reception within a wireless communication device. An antenna tuner controller determines whether the wireless communication device concurrently provides (a) simultaneous signal transmission and reception and (b) dual signal propagation. In response to determining that the wireless communication device concurrently provides the simultaneous signal transmission and reception and the dual signal propagation, the antenna tuner controller determines a current mode of operation corresponding to simultaneous signal transmission and reception and the dual signal propagation. Based on the mode of operation determined, the antenna tuner controller identifies a priority for performing antenna isolation to minimize interference affecting signal reception when the wireless communication device actively communicates within the specific mode of operation. In response to the identifying the priority for performing antenna isolation, the antenna tuner controller performs antenna impedance tuning that provides antenna isolation corresponding to the priority.

1. A method for providing antenna impedance tuning in a wireless communication device having at least one transceiver, the method comprising:
determining if the wireless communication device concurrently provides (a) simultaneous signal transmission and reception and (b) dual signal propagation; in response to determining that the wireless communication device concurrently provides (a) simultaneous signal transmission and reception and (b) dual signal propagation:
determining a mode of operation of the wireless communication device associated with said simultaneous signal transmission and reception and said dual signal propagation, wherein the mode of operation provides an associated interference affecting signal reception within the wireless communication device while the wireless communication device communicates in that mode of operation; andidentifying a priority for performing antenna isolation to minimize interference affecting signal reception when the wireless communication device communicates using the determined mode of operation; in response to the priority for performing antenna isolation being a first priority, performing a first antenna impedance tuning that provides a corresponding degree of antenna isolation, wherein the first priority is greater than a second priority, which second priority triggers a second antenna impedance tuning that provides a lower degree of antenna isolation than the first antenna impedance.
