Description

  The present invention relates to an antenna device, for example, a telephone antenna used in a composite antenna device equipped with a plurality of types of antennas.

  As is well known in the art, various antennas are currently mounted on vehicles. For example, such antennas include a GPS (global positioning system) antenna, an ETC (automatic toll collection system) antenna, a VICS (road traffic information communication system) antenna, a telephone antenna, and the like.

  GPS (Global Positioning System) is a satellite positioning system using artificial satellites. The GPS receives radio waves (GPS signals) from four of the 24 artificial satellites orbiting the earth, and the positional relationship and time error between the moving body and the artificial satellites from the received radio waves. Based on the principle of triangulation, it is possible to calculate the position and altitude of the moving body on the map with high accuracy.

  In recent years, GPS has been widely used in car navigation systems that detect the position of a traveling vehicle. The car navigation device includes a GPS antenna for receiving the GPS signal, a processing device for processing the GPS signal received by the GPS antenna to detect the current position of the vehicle, and a position detected by the processing device. Is displayed on a map.

  On the other hand, ETC (Electronic toll Collection) is a system developed as a measure to alleviate congestion at toll gates for paying tolls on toll roads such as expressways. In other words, ETC is a system that automatically pays tolls using radio communication at an expressway toll gate. In ETC, two-way communication is performed between a roadside antenna provided at a gate installed at a toll gate and a vehicle equipped with an in-vehicle communication device having an ETC antenna to obtain vehicle information of the vehicle. In addition, the highway toll payment service can be performed without stopping the passing vehicle.

  Conventionally, a composite antenna device in which a GPS antenna and an ETC antenna are provided is known (see, for example, Patent Document 1).

  In addition, VICS (Vehicle Information and Communication System) is a roadside station (so-called beacon) provided at predetermined intervals along the road to provide traffic information such as traffic jams and traffic closures to the driver who drives the vehicle. ) And the vehicle. A VICS in-vehicle device mounted on a vehicle includes a VICS antenna and a separate signal processing device connected to the VICS antenna via a cable. As a VICS antenna, an in-vehicle antenna device for road-to-vehicle communication in which a transmission / reception antenna for an optical beacon and a reception antenna for a radio wave beacon are mounted on an antenna substrate is known (for example, see Patent Document 2).

  Furthermore, a composite antenna device including a GPS antenna, a VICS antenna, and an ETC antenna is also known (see, for example, Patent Document 3). In the composite antenna device disclosed in Patent Document 3, the ETC antenna is mounted as a subassembly separate from the circuit board on which the GPS antenna and the VICS antenna are mounted. That is, since the directivity of the ETC antenna is greatly different from that of the GPS antenna and the VICS antenna, only the ETC antenna can be adjusted independently.

  Further, a small and low-profile multi-resonant F-type antenna that can resonate at a plurality of frequencies is known (see Patent Document 4). In the multi-resonance F-type antenna disclosed in Patent Document 4, a radiation plate composed of a first radiation conductor plate and a second radiation conductor plate is disposed on a ground conductor plate at a predetermined interval. The power supply pin supplies high-frequency power to the radiation plate through the ground conductor plate. Since the radiation plate is formed by forming a slit in a planar conductor plate, the double resonance F-type antenna can be made small and low in posture.

  Furthermore, a dual band antenna that can transmit and receive signal waves in two types of frequency bands (bands) and is suitable for use in a vehicle-mounted communication device has been proposed (see Patent Document 5). The dual-band antenna disclosed in Patent Document 5 is a small antenna device that can selectively transmit and receive signal waves in a low band (for example, an 800 MHz AMPS band) and a high band (for example, a 1.9 GHz PCS band). The dual-band antenna disclosed in Patent Document 5 includes an insulating base mounted on a support substrate having a ground conductor on the back surface, a first radiating conductor plate for low band, a feeding conductor plate, A short-circuit conductor plate, a second short-circuit conductor plate, and a high-band second radiation conductor plate are provided. The first radiating conductor plate is provided with the first and second divided conductor plates along with slits, and is mounted at a position where the opening end of the insulating base is closed. The feeding conductor plate and the first short-circuit conductor plate have upper end portions that are continuous with the outer edge of the first divided conductor plate. The second short-circuit conductor plate has an upper end continuous with the outer edge of the second divided conductor plate. The lower end portion of the second radiation conductor plate is connected to the power supply conductor plate. The second radiating conductor plate is erected in the internal space of the insulating base, and the height position is lower than that of the first radiating conductor plate. The second short-circuit conductor plate is electromagnetically coupled to the power supply conductor plate to operate the second divided conductor plate as a parasitic antenna.

  On the other hand, as a wide-band antenna having a wide frequency band such as an in-vehicle cellular antenna, a telephone antenna is also known in which an inverted L element as a feeding element and a parasitic element as a parasitic element are arranged close to each other. In this telephone antenna, it is necessary to transmit and receive signal waves of two types of frequency bands (bands) as disclosed in Patent Document 4 and Patent Document 5.
