Definitions

  • the present invention relates to a circularly polarized patch antenna using a metal patch and a transceiving array antenna using the same; and, more particularly, to a probe feeding-type circularly polarized patch antenna using a metal patch of a simple structure, and a transceiving array antenna using the circularly polarized patch antenna.
  • Figs. 1A and 1B present a cross-section and a perspective view of a conventional circularly polarized patch antenna having a dielectric layer.
  • the conventional circularly polarized patch antenna having a dielectric layer includes a conductive patch 11 formed on the upper surface of the dielectric layer 12 which uses a printed circuit board (PCB), a conductive ground layer 14 formed in the lower surface of the dielectric layer 12. Power is fed to the circularly polarized patch antenna by forming a via hole in the ground layer 14, the dielectric layer 12 and the patch 11 and inserting a connector 13 into the via hole.
  • PCB printed circuit board
  • the flange part of the connector should be connected with the ground layer 14 of the array antennal through soldering. Therefore, the process and structure are complicated and the production cost is high. Therefore, the conventional circularly polarized patch antenna is not suitable for mass production.
  • an object of the present invention to provide a circularly polarized patch antenna which can induce impedance matching and improve axial ratio by using a simple metal radiating patch and a reflection plate and improving the electromagnetic connection characteristics between the reflection plate and the radiating patch.
  • the circularly polarized patch antenna has a simple structure and it can be produced at a low cost.
  • a circularly polarized patch antenna which includes: a radiating unit which is positioned in the upper part of the antenna and has a metal patch for transmitting/receiving circularly polarized signals; a reflecting unit which is positioned in the lower part of the radiating unit with an air layer of a predetermined space from the radiating unit and eliminates rear radiation of the radiating unit; and a power feeding unit for supplying power to the radiating unit.
  • an array antenna using circularly polarized single patch antennas which includes: a plurality of circularly polarized single patch antennas including a radiating unit which is positioned in the upper part of the antenna and has a metal patch for transmitting/receiving circularly polarized signals; a reflecting unit which is positioned in the lower part of the radiating unit with an air layer of a predetermined space from the radiating unit and eliminates rear radiation of the radiating unit; and a power feeding unit for supplying power to the radiating unit in a probe feeding method; and an isolating unit which is positioned between the circularly polarized single patch antennas and prevents the circularly polarized single patch antennas from being coupled.
  • Figs. 2A and 2B present a cross-section and a perspective view of a conventional circularly polarized patch antenna having a metal patch in accordance with an embodiment of the present invention.
  • the circularly polarized antenna using a metal patch which is suggested in the present invention, includes a metal patch 21, a connector 23, and a refection plate 22.
  • the metal patch 21 is set up in the upper surface of the antenna and radiates ultra-high frequency signals into free space.
  • the connector 23 transmits power in the probe feeding method for circular polarization.
  • the metallic refection plate 22 is set up in the lower surface of the antenna, suppresses rear radiation, and fixes the connector 23.
  • a circular groove is formed in the reflection plat 22 as deep as the thickness of a dielectric substance surrounding a connector pin.
  • the reflection plate 22 is put apart by a predetermined space 24 toward an air layer and then connected with the metal patch 21.
  • the metal patch 21 also has a groove formed as deep as the thickness of a pin of the connector 23 and then it is connected with the reflection plate 22.
  • Impedance matching and the axial ratio can be improved by adjusting the space 24 between the reflection plate 22 and the metal patch 21. Also, radiation efficiency can be improved by removing the rear reflection that occurs in the metal patch 21 with the reflection plate 22.
  • Figs. 3A and 3B present a cross-section and a perspective view of a transceiving array antenna using the circularly polarized patch antenna having a metal patch in accordance with an embodiment of the present invention.
  • the circularly polarized patch antenna using a metal patch separates transmission from reception.
  • the single circularly polarized antennas using a metal patch of the present invention are arrayed in two-dimensional on a unit basis.
  • the antenna includes a partition 25 which is located between the metal patches 21, prevents signal coupling during antenna radiation, and maintains the impedance matching and axial ratio the same as the single patch antenna.
  • the power feeding location is made different in adjacent metal patches 21 to thereby generate left hand circular polarization and right hand circular polarization and suppress coupling between array unit antennas. Also, the separation between transmission and reception can be increased by using the left hand circular polarization and right hand circular polarization differently for a transmitting antenna and a receiving antenna.
  • the left one of Fig. 3B is an antenna having the left hand circular polarization characteristic and the right one of Fig. 3B is an antenna having the right hand circular polarization characteristic.
  • the partition 25 between the two antennas eliminates the coupling of the two antennas.

  • the characteristics of the metal patch 21 are different based on the length 25 of the cut-out edge and the location of the connector 23.
  • the length 25 of the cut-out corner affects the impedance matching of a desired frequency and the axial ratio, and the location of the connector 23 affects the impedance matching.
  • the space 24 of the air layer between the reflection plate 22 and the metal patch 21 is related to the impedance matching and the axial ratio, the space 24 should be maintained properly.
  • the cut-out edge 25 is positioned in opposite or, as illustrated in the metal patch 21 on the right part of Fig. 3B, the cut-out edge 25 is maintained, and the location of the connector 23 is moved to the right.

  • the present invention can realize a circularly polarized antenna having a simple structure by using a metal patch for radiation, a reflection plate, and a connector.
