Design of a New Printed Dipole Antenna Using in High Latitudes for Inmarsat

Abstract

A novel printed dipole antenna is designed for the <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">L</i> -band satellite communication system: Inmarsat application (downlink: 1525-1559 MHz, uplink: 1626.5-1660.5 MHz). The proposed antenna was carefully investigated and discussed. The measured results show that the impedance bandwidth for return loss below -10 dB is about 170 MHz, and the half-power beamwidth (HPBW) can be up to 110°. The antenna can be used in the high latitudes thanks to its wide HPBW.
