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.

Antenna-filter module

A dual mode ceramic filter has an enclosure with two cavities separated by a wall, and two TM dual-mode resonators, each TM dual-mode resonator positioned in a corresponding cavity. Each TM dual-mode resonator has first and second modes, and a body having a central portion with a plurality of arms extending outwardly from the central portion. The filter also has two input conductive members, each input conductive members positioned in a corresponding cavity. Each input conductive member is disposed proximate a corresponding TM dual-mode resonator for coupling between the input conductive member and the TM dual-mode resonator.
