1. A mobile communication device comprising:
- a housing, the housing comprising;
a front housing portion configured to contain an actuator sensor; and
a rear housing portion being made of a rear housing material and having an inside and an outer side, the rear housing portion further comprising an actuator configuration on the inside that is configured to be sensed by the actuator sensor when the front housing portion and the rear housing portion are combined to establish the housing;
the actuator configuration adapted to be sensed by the actuator sensor so as to indicate that the rear housing material is a particular material.

Abstract
A UE is provided having a front housing and a rear housing. The rear housing is made of a material that affects the operation of an antenna when operating at different frequency bands. The rear housing includes an actuator configuration that is sensed by an actuator sensor within the housing when the housing is assembled. The actuator configuration indicates the material used to construct the rear housing. Upon sensing the actuator configuration, the UE is configured to tune the antenna for efficient operation at the operating frequency band while proximate to the rear housing.

13. A method of tuning an antenna in a mobile communication device comprising a housing material being one of a plurality of housing materials, the method of tuning comprising:
-
powering on a transceiver in the mobile communication device; sensing, by an actuator sensor, an actuator configuration located on an inside of a mobile communication device housing; providing, by the actuator sensor, a material type signal; using the material type signal to determine a material type and providing a tuning signal, the tuning signal being one of a plurality of predetermined tuning signals based on the material type and a frequency band being used by the transceiver; tuning an antenna tuner to match an impedance between the transceiver and the antenna for the housing material and the frequency band being used by the transceiver. - View Dependent Claims (14, 15)
