Definitions
- the present invention relates to a dual band dual polarization antenna for diversity in a base station antenna of mobile communication (PCS, Cellular, IMT-2000, etc.).
- Antennas for mobile communication base stations are designed using spatial diversity or polarization diversity to reduce fading.
- the spatial diversity method is to install a transmitting antenna and a receiving antenna spaced apart by a predetermined distance, which is not only limited in terms of space but also in terms of cost. Accordingly, the mobile communication system generally uses a dual band dual polarized antenna by applying a polarization diversity scheme.
- Dual-band dual polarization antennas are used to transmit (or receive) two linear polarizations that are aligned at right angles to one another, for example vertically and horizontally. However, in practical applications it is very important to operate these antennas to align this polarization to +45 degrees and -45 degrees with respect to the vertical (or horizontal). Dual band dual polarization antennas generally operate in two frequency bands that are sufficiently spaced apart from one another. For such a dual band dual polarized antenna, there is exemplified what is disclosed in Korean Patent Application No. 2000-7010785 (name: dual polarized multiband antenna) filed by Katline-Berke Cage.

- each of these dipole elements 1a is precisely aligned at angles of +45 and -45 degrees with respect to the vertical (or with respect to the horizontal) to form a bipolar antenna, referred to simply as an X-polarized antenna.
- the second radiating element module 3 may be located in or outside the first radiating element module 1 in the form of a square dipole.
- the second radiating element module 3 is not a square dipole but a cross dipole.
- the two dipoles 3a positioned at right angles to each other are likewise supported on the reflecting plate 5 through the balance net, and are fed through them.
- the first and second radiating element modules 1 and 3 are precisely arranged at different distances in front of the reflecting plate 5. At this time, the second radiating element module 3 is arranged to be interleaved with the first radiating element module 1.
- two antenna devices formed by the first and second radiating element modules 1 and 3 may be installed on the reflecting plate 5 in the vertical direction, and two antenna devices.
