Abstract:
The present invention relates to an antenna-filter module for transferring radio frequency electromagnetic signals between the ambient air and an electronic circuit. The module includes an antenna element and at least two integrated band pass filter disposed adjacent to said antenna element. The antenna element is arranged as a joint antenna element, having a substantially greater bandwidth than each filter and providing a number of antenna-filter combinations within the module. The joint antenna element is arranged in close proximity to a first resonator of each filter in the module so as to provide an electromagnetic coupling to the resonators of each filter and a differentiated, specific pass band for the respective antenna-filter combination. Each filter is provided with a coupling member for coupling to an electronic circuit, such as an amplifier.
