Claim:
1. A communication device comprising: a memory that stores a group of tuning parameters indexed to detected use cases of the communication device; an antenna having a radiating element and a feedpoint; a first tunable element directly connected with the radiating element of the antenna for tuning the antenna, wherein a first adjusting of the first tunable element comprises an open loop process and is based on a tuning parameter of the group of tuning parameters that is indexed to a detected use case of the communication device, and wherein a plurality of adjusting operations of the first tunable element, performed after the first adjusting, comprise closed loop processes and are based on measurement of one or more operational parameters of the communication device, wherein the first adjusting of the first tunable element is not based on measurement of the one or more operational parameters; and a matching network having a second tunable element and being coupled to the feedpoint of the antenna, wherein the matching network receives control signals for adjusting the second tunable element to tune the matching network.
