Title

A Small Printed Quadrifilar Helical Antenna for BGAN/GPS Applications

Pages

  7-11

Abstract

 This paper presents an element of a 2×2-element array antenna for Inmarsat BGAN/GPS applications. The element is an axial mode Printed quadrifilar helical antenna that has been integrated with a compact feed network to provide sequential phase rotation for circular Polarization (CP) radiation. The novel integrated lumped-element feed network is designed to provide a balanced RF power to the four helix arms with a 90° sequential phase difference between them. The design maintains a low cross Polarization, and accordingly, a high quality of RHCP up to ± 66° over the transmit frequency band of 1616 MHz to 1626 MHz. The gain in this frequency range is higher than 3. 5 dB with a return loss better than 11 dB and a perfect circular Polarization performance (axial ratio ~0 dB). The proposed antenna has small size, light weight, low cost, almost hemispherical radiation pattern and excellent circular Polarization that can become a good candidate in satellite L1-band and BGAN satellite communications.
