A novel printed dipole antenna was designed for the L-band satellite communication system INMARSAT (Downlink: 1525--1559 MHz, Uplink: 1626.5--1660.5 MHz). Several structural parameters were experimentally studied with care to establish a design procedure. The measured results show that the impedance bandwidth for return loss below -10 dB is about 170 MHz and that the half-power bandwidth (HPBW) can be up to 110°. The antenna can be used in high latitudes because of wider HPBW.
