Abstract :
Antennas for ships, aircraft, and land-mobiles have been developed under ESA (European Space Agency) funding for communications at 1.5/1.6 GHz via satellites. The EMS payload on Italsat F2, followed by the multibeam LLM (L-band land mobile) payload on the ESA ARTEMIS satellite, will provide coverage of Europe in 1995 from geosynchronous orbit. Coverage of users at elevations down to 10/spl deg/ limits the use of low profile designs. This, and for voice communications the needed sidelobe isolation towards neighboring satellites, limits the scope for downsizing the mobile antennas. Both omnidirectional antennas for data transmission and directive ones for voice communications are described.<>
