The Design of Compact Printed Quadrifilar Helix Antenna
摘要
Abstract
A new design is used to reduce the size of the traditional Printed resonant Quadrifilar Helix Antenna (PQHA) so that the area of the feed network is reduced by 50％ and the isolation resistor isn't needed. The effect of helix parameters on the performances is analyzed and then the design is presented.The agreement between the simulated and measured results and a 3 dB axial ratio beamwidth of 171° are achieved, confirming the validity of the design.关键词
