Definitions

  • the present invention relates to telecommunication systems and, more specifically, to antennas and equipment for transmitting and receiving radio communication signals.
  • Radio equipment such as radio transceiver devices for use in mobile and cordless telecommunication systems, often comprise micro strip patch antenna structures, connected to electronic circuitry using separate external wiring, such as coaxial cable, for example.
  • European patent 0 383 292 discloses an electronic circuit device having a micro strip patch antenna formed on a Printed Circuit Board (PCB).
  • the PCB comprises a first surface on which a wiring track pattern is formed and on which components are mounted.
  • a second surface of the PCB comprises a ground plane, part of which is formed as a coupling stub for feeding a radiator patch which is mounted opposite the ground plane at a distance thereof.
  • a feed point of the coupling stub connects by a plated through hole to the wiring pattern on the first surface of the PCB.
  • impedance matching circuit For impedance matching of the coupling stub with a transceiver circuit, a separate impedance matching circuit is required.
  • This impedance matching circuit occupies space on the PCB which, among others, is determined by the type of matching circuit and the wavelength for which the impedance should be matched. Those skilled in the art will appreciate that for relatively large wavelengths, the matching circuit may occupy a relatively large space on the PCB, thereby reducing the effective occupancy of the PCB.
  • an as high as possible occupancy of the PCB is to be demanded.
  • radio transceiver means such as a radio access unit and a radio communication unit for mobile or cordless radio communication systems.
  • radio transceiver means such as a radio access unit and a radio communication unit for mobile or cordless radio communication systems.
  • an improved micro strip patch antenna for use in radio transceiver means equipped with two or more antennas arranged for applying antenna diversity in order to improve radio link performance of the radio transceiver means.

  • Such an antenna can be used, among others, for dual band transceiver devices, which can transmit and receive signals simultaneously onto separate frequency bands, using one radiator patch for the frequency bands. It will be appreciated that this type of antenna is of advantage for reducing the dimensions of radio transceiver devices.
  • each feed structure comprises a separate feedline and a separate associated aperture.

  • This embodiment of the patch antenna according to the present invention is characterised by a very high isolation between the two feed structures, thereby avoiding unwanted mixing effects between the different feed structures.
  • the radiator patch i.e. the third layer of the patch antenna
  • the third layer forming the radiator patch is arranged with a housing comprising the antenna. That is, the radiator patch can be connected to or even may form part of the (plastic) housing. In both cases, air may be used as dielectric material between the radiator patch and the feed structure.
