摘要：

A new approach to designing a handset antenna for satellite applications is reported. It is based on precise control of the phasing between two bifilar helices, giving accurate resonant frequency position and radiation pattern volute. Results show an antenna with a gain of-2 dBi, 19 dB discrimination between the right and left hand circular polarisations and an axial ratio less than 1dB. The front-to-back ratio is 24 dB. A return loss of 14.6 dB is also measured.
