Definitions

  • the present invention relates to an antenna system, and more particularly, to a switchable antenna system capable of being switched arbitrarily between a built-in antenna mode and an external antenna mode.
  • An antenna is an essential wireless communication device for transmitting and receiving electromagnetic signals.
  • a transmitter of a wireless communication system outputs a radio frequency (RF) signal to the antenna via a conducting wire, and the antenna emits the RF signal in an electromagnetic form.
  • RF radio frequency
  • antennas In order to comply with transmissions of various frequencies, functions and circumstances, the industry has developed various types of antennas. These types of antennas can be classified in different ways. If the classification is based on functionality, the antennas can be divided into communicative antennas, television antennas, radar antennas, etc. If the classification is based on operating frequency, the antennas can be divided into short wavelength antennas, ultra-short wavelength antennas, microwave antennas, etc. If the classification is based on directionality, the antennas can be divided into omni antennas, directional antennas, etc. If the classification is based on appearance, the antennas can be divided into linear antennas, planar antennas, horn antennas, etc. In general, the antennas can be built-in or external, and the user can select a desired antenna type according to requirements or using purposes.
  • the wireless communication system may only support one antenna mode.
  • the wireless communication system utilizing the built-in antenna may not support the external antenna, and the wireless communication system in which the external antenna is required may not possess functionality of the built-in antenna.
  • the user wants to change to use an external high power antenna because performance of the built-in wireless antenna is poor, or wants to use a directional antenna in order to enhance signal coverage due to special topography, since the above limitation of the antennas, the user is not allowed to arbitrarily change the working status of the antenna.
  • the application aims at providing a switchable antenna system in order to solve the abovementioned problems.
