Abstract

In this paper an antenna for the L-band satellite communication system INMARSAT is presented. The INMARSAT System (Downlink: 1525-1559 MHz, Uplink: 1626.5-1660.5 MHz) was mainly build for voice and data communication between offshore ships and the mainland. Therefore these antennas have to have a steerable beam, so they can be pointed to the satellite regardless of the ships position on sea, as well as to compensate for the movement of the ship itself. So far the antennas for such systems have been steered mechanically. In this paper a new, cost effective and electronically steerable conformal array antenna for the INMARSAT system is presented.
