A S-band Printed Quadrifilar Helical Antenna for Communication Devices

摘要：

　　It was mainly analysed a S-band printed quadrifilar helical antenna for communication devices in this paper.And a dielectric loaded wide beam printed quadrifilar helical antenna was designed.A two-stage isolation resistor was placed in wilkinson power divider.The simulation results of this antenna agree well with the measured results.According to the simulation results and measured results,the antenna had a good heart-shaped radiation pattern from 3.05GHz to 3.45GHz,3dB power-width was more than 160°,the gain was greater than-2dB in the azimuth range,the axial ratio was lower than 5dB,and the VSWR was lower than 1.4.this printed quadrifilar helical antenna had good electromechanical characteristics,and low cost.
