  • FIG. 24 is a diagram showing a manufacturing process of the antenna element shown in FIG. That is, the feeding terminal 392 of the antenna element 39 is integrally formed with the reinforcing member 3 by punching, and is formed in a U shape as shown in FIG.
  • the U-shaped power supply terminal 392 is first folded at a folding position B1 shown in (a) as shown in FIG. 24, and then folded at a folding position B2 shown in (b) as shown in (c). Then, it is folded at the folding position B3 shown in (c) and formed in the state shown in (d).
  • FIG. 25 is a side view showing a state before the power supply pad is installed
  • FIG. 26 is a side view showing a state after the power supply pad is installed.
  • the power supply terminal 392 bent in the J shape of the antenna element has a base end portion 393 fixed to the front cover 1 with an adhesive or the like.
  • the 1st member 52 which consists of a dielectric material or a magnetic body is installed, you may make it fix to this 1st member 52.
  • the antenna adjustment board 8 (not shown in FIG. 26) on which the power supply pad 81 is formed is installed on the upper surface of the reinforcing member 3.
  • the tip of the power supply terminal 392 is lifted upward as shown by the arrow in FIG. 26, and the antenna adjustment substrate 8 is inserted into the gap between the reinforcing member 3 formed thereby and the power supply terminal 392. Therefore, the power supply terminal 392 is pressed against the power supply pad 81 of the antenna adjustment substrate 8 by the elastic force generated by itself, and thereby a desired contact force is exhibited.
  • the shape of the antenna element is not limited to the inverted F type and the E type, and various other shapes can be considered.
  • the formation position of the antenna element with respect to the reinforcing member 3 is not limited to one side, and may be a plurality of sides.
  • a plurality of antenna elements 301 and 302 for folded antennas are integrally formed on a plurality of different sides of the reinforcing member 3.
  • the antenna elements 301 and 302 are respectively bent appropriately and are arranged along different surfaces of the inner surface of the housing as shown in FIG.
  • the rigidity of the antenna element 301 for the folded antenna can be improved, thereby reducing the occurrence of breakage and the like.
  • the antenna element 32 when the antenna element 32 is disposed in contact with the inner surface of the front cover 1, the antenna element 32 is attached to the inner surface of the front cover 1 with a double-sided tape, an adhesive, or the like. It is good to make it integrate using resin etc. If it does in this way, the function as a reinforcement member of the side part of the front cover 1 can further be improved.
  • the shape of the antenna element is left by punching the reinforcing member 3, but instead of forming the antenna element, a slit is similarly formed in the reinforcing member 3 by punching to supply power. May be performed. In this way, a slot antenna using a slit can be configured.
  • slits may be formed in the reinforcing member so as to have a predetermined positional relationship. If it does in this way, isolation between a plurality of antenna elements can be raised with a slit.
  • an antenna element and a slot antenna using a slit may be formed on the reinforcing member.

Abstract

Un boîtier destiné à un dispositif de communication sans fil loge une carte de circuit imprimé sur laquelle un composant électronique est monté, un élément de renfort conducteur destiné à renforcer au moins le boîtier ou la carte de circuit imprimé et une antenne. L'antenne est équipée d'un élément d'antenne et d'une unité d'alimentation. L'élément d'antenne fait partie intégrante de l'élément de renfort conducteur et utilise l'élément de renfort conducteur en tant qu'élément de terre. L'unité d'alimentation fournit des signaux radioélectriques à l'élément d'antenne.
