A Compact Dual-Band Assembled Printed Quadrifilar Helix Antenna for CNSS Application
This paper presents a novel compact dual-band printed quadrifilar helix antenna (PQHA) for application in Compass Navigation Satellite System (CNSS) of China.This antenna is consisted of two quadrifilar helix elements that are arranged at inner and outer cylinder.It works at the B1(1.561GHz) and S (2.492GHz) bands.Each four spiral arms is excited by a series feed network in equal magnitude and successive 90° phase difference.It achieves the axial radiation pattern at B1 band, furthermore, it produces the shaped-conical radiation pattern at S band that is benefit for receiving the navigation signal from low elevation angle.Simulations show that10dB impedance bandwidth of the proposed novel compact CNSS dual-band PQHAs are 15.4% at B1 band and 14.2% at S band.in addition, the axial ratio bandwidth is less than 3 are 12.8%and 2.8% at BI and S band, respectively.The isolation between two quadrifilar helix elements is higher than 27dB.
