Quadrifilar Helix Antenna Size Reduction by Mender Line Technique for GPS Applications

THE most widely proposed hand-held antenna for mobile satellite communication systems is the Quadrifilar Helix Antenna (QHA). The QHA is preferred to the crossed dipole and the patch for its small structure, insensitivity to ground or hand proximity effects, easily shaped radiation pattern, and wide circularly polarized beam. A method to reduce the axial length of a conventional Printed Quadrifilar Helix Antenna (PQHA) using a meander line technique is described. The design approach and the measurement results for the Meander Printed Quadrifilar Helix Antenna (MPQHA) are presented.
