ANTENNA APPARATUS FOR SATELLITE COMMUNICAITON IN MOBILE TERMINAL

摘要

PURPOSE: An antenna apparatus for satellite communication in a mobile terminal is provided to improve an antenna characteristic by using an auxiliary antenna. CONSTITUTION: A circular polarization antenna(221) transceives a satellite communication signal. A satellite communication module part(220) is electrically connected to the circular polarization antenna and performs satellite communication. A cellular antenna(211) transceives a cellular communication signal. An auxiliary antenna(222) is selectively connected to the circular polarization antenna and an electrical connection structure of the satellite communication module part through a switching device(223). A control unit(201) controls the switching device.
