Summary:An antenna arrangement for the base unit of a cordless telephone which consists of separate antennas for transmission and reception. A whip antenna is used for transmission, whereas the telephone Tip/Ring wiring is used for reception. The telephone Tip/Ring wiring operates as an antenna with a moderate distributed capacitance to ground. Radiation from the handset can be acquired almost anywhere along the house telephone wiring and can be then conducted to the cordless telephone base receiver by the same wire. Therefore, the telephone wiring serves dual purposes as an antenna and as a feed-line. Because the transmitter and the receiver of the antenna arrangement are isolated, the receiver input filter is simple and easy to tune. The transmitting whip antenna is considerably smaller than the conventional whip antenna used for both transmission and reception, and its filters are also easier to tune than when used in a duplexer configuration.
