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.

Method and apparatus for radio frequency tuning utilizing a determined use case

A tri-band antenna for noncellular wireless applications is provided. The antenna comprises: a first radiating arm for generating a first resonance in a first frequency band, the first radiating arm further enabled for connection to an antenna tuning circuit; the first radiating arm comprising a capacitive coupling structure; a coupling arm separated by a gap from the first radiating arm; a second radiating arm for generating a second resonance in a second frequency band lower than the first frequency band, the second radiating arm connected to the coupling arm such that the second radiating arm is capacitively coupled to the first radiating arm; and a third radiating arm for generating a third resonance in a third frequency band lower than the second frequency band, the third radiating arm connected to the coupling arm such that the third radiating arm is capacitively coupled to the first radiating arm.
