abstract = "A new printed square quadrifilar helix antenna (QHA) for circular polarization (CP) is proposed and experimentally investigated for the application as a GPS receiving antenna in frequency range of about 1.575 GHz. To increase the input impedance of QHA, we use the folded inverted-F antenna as a helix. Experiment results show that the proposed antenna has a 3-dB beamwidth of more than 120° and a front-to-back ratio of more than 15 dB. Also, the proposed antenna shows the peak gain of -2.5 dBic and the axial ratio under 0.5 dB in wanted frequency band.",
