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 (2c) and a ground terminal (2d) at the end portion where the support portion (4) is mounted. The power supply terminal (2c) and the ground terminal (2d) are connected to an antenna terminal (4a) and the ground terminal (4b) of the laminated circuit, respectively. The radiation member (2) has a radiation electrode (2a) where a slot (2b) is formed. The shape of the slot is set so that the radiation electrode (2a) causes resonance in a plurality of frequency bands.
