Title:

DUAL POLARIZATION ANTENNA INCLUDING ISOLATION PROVIDING DEVICE

Document Type and Number:

WIPO Patent Application WO/2014/027842

Kind Code:

A1

Abstract:

The present invention relates to a dual polarization antenna including an isolation providing device including: a transmission antenna element outputting a transmission signal provided via a feeder through a first port; a receiving antenna element receiving a reception signal so as to provide same to the second port; a first coupler distributing part of the transmission signal; an equalizer equalizing the distributed signal from the first coupler to a preset waveform; a second coupler receiving the output of the equalizer so as to couple same to a signal output to the second port; and a conductor forming a signal delivery path between the first coupler, the equalizer, and the second coupler. The coupling performance of the first and second couplers, the length of the conductor, and the functional characteristics of the equalizer are designed to allow a signal coupled to the second port through the signal delivery path using the conductor to have substantially identical amplitudes and a 180° phase difference, and an identical shape in an overall operating frequency band in contrast to a signal falsely inputted to a receiving antenna from the transmitting antenna element.
