Antenna device and method for transmitting and receiving radio waves
First Claim
1. An antenna device for transmitting and receiving radio frequency waves, installable in a communication device, and comprising:
- an antenna structure switchable between a plurality of antenna configuration states, each antenna configuration state being distinguished by a set of radiation parameters;
a switching device which selectively switches said antenna structure between said plurality of antenna configuration states;
a first receiver which receives a first measured operation parameter indicative of quality of transmission of radio frequency waves by said antenna structure;
a second receiver which receives a second measured operation parameter indicative of quality of reception of radio frequency waves by said antenna structure; and
a control device which controls said switching device, and thus selective switching of said antenna structure between said plurality of antenna configuration states, in accordance with said received first and second measured operation parameters, so as to improve quality of at least one of transmission and reception of the antenna structure.

Abstract
An antenna device for transmitting and receiving radio frequency waves, installable in a communication device includes an antenna structure switchable between antenna configuration states. Each state is distinguished by a set of radiation parameters, such as resonance frequency, input impedance, bandwidth, radiation pattern, gain, polarization, and near-field pattern. A switching device selectively switches the structure between the states. The antenna device includes a first receiver which receives a first measured operation parameter indicative of quality of transmission of radio frequency waves by the antenna structure, and a second receiver which receives a second measured operation parameter indicative of quality of reception of radio frequency waves by the structure. The antenna device includes a controller which controls the switching device, and selective switching of the antenna structure between the states, based on the first and second measured operation parameters, to improved transmission and/or reception quality.
