Description

    Field of the Invention
  • The present invention is related to a communication device antenna utilizing a metal housing for emitting and receiving radio signals of a communication device according to the pre-characterizing clause of claim 1.
    • Background of the Invention
  • During product development processes of conventional communication devices, such as mobile communication products, plastic housings are mainly used by manufacturers due to cost concerns, in order to maintain basic radiation characteristics of an antenna. However, a trend of metal housing is currently brought by Apple iPhones and Macbooks. Since the metal housing has light weight, good heat dissipation, high strength, high impact resistance, good looking, anti-electromagnetic and recyclable characteristics, the metal housing is getting more and more popular. Therefore, the metal housings are mainly used in development of new generations of the mobile communication products. For example, US patent No. 8,054,231 B2 disclosed by Ahn et al. teaches a metal case having a slot, which can be used as a slot antenna of a mobile device. But the slot may obviously ruin appearance of the metal case, and the slot needs to be arranged at a position corresponding to a specific area of the metal case. Therefore, it is important to design a proper antenna to allow electromagnetic waves to penetrate the metal case for achieving communication purposes without obviously ruining the appearance of the metal case.
    • Summary of the Invention
  • This in mind, the present invention aims at providing a communication device antenna utilizing a metal housing for emitting and receiving radio signals of a communication device.
  • This is achieved by a communication device antenna according to claim 1. The dependent claims pertain to corresponding further developments and improvements.
  • As will be seen more clearly from the detailed description following below, the claimed communication device antenna comprises a metal housing, a signal feed point, a ground point and an excitation component. The metal housing has a first lateral side, a second lateral side corresponding to the first lateral side, and a connection side extended and connected between the first lateral side and the second lateral side, wherein an opening is formed and located adjacent to the connection side. The excitation component is connected to the signal feed point and the ground point, wherein a coupling gap is defined between the excitation component and the connection side of the metal housing.
