First Claim
Patent Images
1. A communication device, comprising:
- a first antenna;
a second antenna;
a tunable compensation circuit;
a first circuit coupled to the first antenna;
a second circuit coupled to the second antenna; and
a controller coupled to the tunable compensation circuit, and the first and second circuits, wherein responsive to executing computer instructions, the controller performs operations comprising;
causing a transmission of a reference signal from the first antenna;
receiving a signal from the second antenna, wherein the signal is associated with the reference signal transmitted by the first antenna;
determining from the received signal one or more compensation parameters; and
tuning the tunable compensation circuit according to the one or more compensation parameters, wherein the one or more compensation parameters set a variable impedance or variable circuit configuration of the tunable compensation circuit to reduce the mutual coupling between the first and second antennas.

Abstract
A system that incorporates teachings of the subject disclosure may include, for example, a method for comparing a received signal from a first antenna to a reference signal transmitted by a second antenna, determining from the comparison one or more compensation parameters, and tuning a compensation circuit according to the one or more compensation parameters, where the one or more compensations parameters configure the compensation circuit to reduce mutual coupling between the first and second antennas. Other embodiments are disclosed.
