Abstract
Abstract An approximately rectangular plate-shaped radiation member ( 2 ) is provided and support portions ( 4,6 ) are attached to lower surface end portions adjacent to a pair of parallel shorter sides of the radiation member ( 2 ). The support portion ( 4 ) is composed of a laminated circuit member including a laminated demultiplexer and a laminated band pass filter of the reception side and the transmission side respectively connected to the laminated demultiplexer. The radiation member ( 2 ) has a power supply terminal ( 2 c ) and a ground terminal ( 2 d ) at the end portion where the support portion ( 4 ) is mounted. The power supply terminal ( 2 c ) and the ground terminal ( 2 d ) are connected to an antenna terminal ( 4 a ) and the ground terminal ( 4 b ) of the laminated circuit, respectively. The radiation member ( 2 ) has a radiation electrode ( 2 a ) where a slot ( 2 b ) is formed. The shape of the slot is set so that the radiation electrode ( 2 a ) causes resonance in a plurality of frequency bands.
