摘要： Dielectric sheets (31) each having a conductor film on one side are so stacked as to constitute at least one filter (2), so that a multilayer dielectric block (3) is produced. A radiation element (1) is provided on the laminated dielectric block (3), and one electrode of the filter (2) is electrically connected to the radiation element (1). The other electrode of the filter (2) is led out to the mount face (B) (the face opposite to a circuit board to be mounted) of the multilayer dielectric block (3) through a via contact (33) and a wiring (34) so as not to be exposed on the side face, and connected to a feeding terminal electrode (4) provided on the mount face. As a result, an antenna with a built-in filter of the structure where even if it is mounted on a circuit board, interference between an electronic circuit on the circuit board and the feeding terminal electrode of the antenna is prevented to improve the isolation characteristic and transmission/reception characteristic.

摘要： 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.

摘要： An antenna for mounting on a vehicle which restrains damping of a signal voltage by reducing a stray capacitance of a signal path and has an improved antenna characteristic and a short physical length, and an antenna element which is suitable for an antenna for mounting on a vehicle and is flexible by using a helical coil of a large winding diameter are provided. In the antenna for mounting on a vehicle, with respect to a band signal having a short wavelength of a plurality of band signals to be transmitted/received, an antenna element (10) is caused to resonate with a physical length shorter than ¼ of the wavelength of the band signal. A linear line portion (12) is provided at the proximal end, and the antenna element (10) is provided at a predetermined distance from a vehicle body (14) and a conductive member of the same electric potential as the vehicle (14). The stray capacitance between the proximal end portion of the antenna element (10) and the vehicle body (14) is small, and a signal voltage is outputted without being damped. The antenna element (10) is formed by burying a helical coil (48) coaxially into a flexible insulating resin pipe (44). The pitch of the helical coil (48) is not shifted even when it is bent repeatedly. Also, no sink mark is generated in the insulating resin pipe (44).
