Abstract

A system that incorporates teachings of the present disclosure may include, for example, a memory, a transceiver, a plurality of antennas coupled with the transceiver, a matching network coupled with at least one of the plurality of antennas, a detector coupled with the matching network where the detector obtains operational data associated with at least two of the plurality of antennas, and a controller circuit coupled with the detector and the matching network. The controller circuit can analyze the operational data to determine an operational data differential between the at least two of the plurality of antennas. The controller circuit selects a use case for the communication device from among a group of use cases stored in the memory based on the operational data differential. Additional embodiments are disclosed.

First claim

What is claimed is:

1. A mobile communication device comprising:
a transceiver;
a first antenna and a first matching network coupled with the transceiver, wherein the first matching network includes a first tunable element with a variable reactance for impedance tuning, wherein the first matching network is tuned to an initial state;
a second antenna and a second matching network coupled with the transceiver, wherein the second matching network includes a second tunable elemen…
