摘要： 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.

摘要： The present invention relates to a method and an arrangement for optimizing the efficiency of a power amplifier (1) that is utilized for transmission of radio signals in a portable radio communication device, such as a mobile phone. The impedance loading the power amplifier (1) is controlled by a controller (5) in dependence on a transmission power of the portable radio communication device, wherein the radiating impedance of an antenna element (2) loading the power amplifier is controlled in dependence of the desired load impedance. Preferably, the changing of radiating impedance is performed by changing a capacitive coupling between the antenna element and a ground element or by changing the size of the antenna element. Better efficiency and bandwidth are thereby attained.
