Definitions

  • the present invention relates to a compact antenna device suitable for in-vehicle use and so on, and more particularly, to an antenna device in which an antenna main body having a patch antenna structure and a circuit board with a low noise amplifying circuit and so on mounted thereon are unitized and housed and held in a radome.
  • an antenna device has been increasingly demanded as an antenna for an ETC (electronic toll collection system) or an antenna for a GPS (global positioning system) to be mounted on a mobile, such as a vehicle or the like.
  • ETC electronic toll collection system
  • GPS global positioning system
  • such an antenna device generally has a configuration in which an antenna unit is housed in a case having a pair of upper and lower radomes, and the antenna unit is connected to an external circuit through a coaxial cable.
  • the antenna unit schematically has a circuit board with a wiring pattern or a semiconductor component mounted on a lower surface thereof, an antenna main body, such as a dielectric patch antenna or the like, that has a radiating conductor and is mounted on the circuit board, and a shield case, formed of a metal plate, that is mounted so as to cover the lower surface of the circuit board.
  • a feeding point of the radiating conductor and the wiring pattern of the circuit board are connected to each other by a feeding pin.
  • the shield case is connected to a ground through an outer conductor of the coaxial cable.
  • the shield case prevents unwanted radiation of a low noise amplifying circuit having a wiring pattern or a semiconductor component from adversely affecting on antenna characteristics and prevents interfering waves coming from the outside from adversely affecting on the low noise amplifying circuit.
  • the antenna device having the above-described configuration in which the case of the antenna unit has a pair of synthesized resin radomes (upper and lower radomes) needs to prepare individual dedicated molds for both radomes, case cost is increased and thus it is difficult to reduce manufacturing costs of the entire device.
  • an antenna device has been proposed in which a metal plate cover covers the bottom opening of one radome housing an antenna unit so as to reduce case cost, such that the antenna device can be manufactured at low cost (for example, see JP-A-7-326914 (pages 2 and 3, and FIG. 2)). Further, according to the related art, the antenna device can be easily mounted at an arbitrary place of a metal exposed portion or a metal embedded portion in a vehicle by incorporating a magnet in a recess formed in the metal plate cover.
  • the manufacturing costs of the antenna device can be reduced by combining the metal plate cover with the radome.
  • the semiconductor component mounted on the circuit board may be easily damaged by static electricity. That is, since the metal plate cover and the radiating conductor of the antenna main body are disposed substantially in parallel with each other and function as a parallel plate capacitor, there is a possibility that excessive induced current caused by the static electricity applied to the cover flows from the radiating conductor into the wiring pattern of the circuit board and thus the semiconductor component is destroyed.
  • it is conceivable to additionally provide a circuit for preventing electrostatic breakdown in the circuit board but, in this case, the circuit configuration becomes complicated, costs may be increased. Accordingly, cost reduction using the metal plate cover is lost.
  • the invention has been finalized in view of the drawbacks inherent in the related art, and it is an object of the invention to provide an antenna device that can be manufactured at low cost and can prevent electrostatic breakdown.

  • the antenna unit is connected to an external circuit through the coaxial cable.
  • the case has a synthesized resin radome that houses, holds, and covers the antenna unit, and a metal cover that covers a bottom opening of the radome, through which the shield case is exposed in a projecting manner.
  • the shield case and the metal cover facing each other are connected to each other.
  • the static electricity can rapidly escape to the shield case. Therefore, electrostatic breakdown of the semiconductor component mounted on the circuit board can be prevented.
  • a tongue piece provided in the shield case be brought into elastic contact with the metal cover.
  • the connection between the shield case and the metal cover can be very simply implemented.
