HOME REPEATER HAVING A HELICAL ANTENNA CAPABLE OF EQUIPPING A LINK ANTENNA AND A SERVICE ANTENNA TOGETHER WITHIN A CASE OF THE REPEATER BY ENHANCING ISOLATION BETWEEN THE LINK ANTENNA AND THE SERVICE ANTENNA

摘要

PURPOSE: A home repeater having a helical antenna is provided to improve isolation between a link antenna and a service antenna by generating a radio signal of the same circular polarization in the link antenna and the service antenna of the repeater.;CONSTITUTION: A link antenna(31) transceives a signal with a base station. A service antenna(32) transceives a signal with a mobile communication terminal. A repeater circuit(33) amplifies a bidirectional signal between the link antenna and the service antenna. The link antenna and the service antenna generate a radio signal of circular polarization. A spiral helical antenna is used as the link antenna and the service antenna.;COPYRIGHT KIPO 2010
