A novel printed dipole antenna is designed for the L-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.
