The Design and Fabrication for Wireless Repeater Patch Antenna of Wide-band Dual polarization

Abstract

In this paper, a dual polarization patch antenna operates at the wide bandwidth of 1.525GHz∼1.665GHz was designed and fabricated. To obtain the wide bandwidth and high gain, increas ed height of air floor from GND was applied, and to get wide band axial ratio and high gain, parasitic patch was applied. The simulation and measurement showed good agreements, the VSWR was less than 1.9 at the frequency bandwidth, the return loss was less than –10dB, and the LHCP(Left Hand Circular Polarization) and RHCP(Right Hand Circular Polarization) isolation was less than –13dB at the frequency bandwidth.
