The present invention relates to antenna arrangements for radio communications devices including cordless phone handsets and base stations. The handset includes an antenna arrangement incorporating one or more batteries as part of a monopole structure. The base station includes an antenna arrangement incorporating a low voltage power supply cable. Both handset and base station may also optionally further incorporate an antenna structure located in the split line between their respective casing components.

Radio communication device antenna arrangements

A kit for converting to cordless operation a telephone having a corded handset and a base unit, the base unit having a handset connector jack and a handset receiving cradle for matingly cradling the handset and the corded handset having a housing, a microphone, a speaker, and a cord for electrically connecting the handset to the handset jack. The kit includes a module having a fastener for fixing the module in mating engagement with the base unit and a connector for electrically connecting the module to the handset jack. An uncorded handset mating with the handset receiving cradle is provided, the uncorded handset having a housing generally matching that of the corded handset. The module and uncorded handset exchange signals via radio transmitters and receivers and contain switches responsive to cradling and uncradling of the uncorded handset so that the converted telephone operates as if the uncorded handset remained connected by a handset cord to the base, while the overall shape and configuration of the telephone is preserved.

Corded to uncorded telephone conversion kit

An interactive cordless telephone handset having an alphanumeric data display system is in radio communication with an associated base station to which voice and data signals are conducted over a telephone line. Received caller identification data is tested for validity and is stored in a limited storage Callers List memory of the base station if found valid. Subsequently, the data is transmitted to the handset over a radio link of limited range, with the received data being formatted and conducted to a display screen for identifying the caller by name and telephone number prior to answering the call. Although caller identification is erased from the display after the call, it is retained in the Callers List memory of the base station where it may be accessed by the handset via softkeys and dedicated dialpad keys for subsequent display and editing and optional transfer to a general directory for long term storage in a non-volatile memory of the base station.
