Title: An antenna system
IPC: H01Q5/357
Filed: 1996-03-29
Abstract: In an antenna system for radio signals in at least two spaced-apart frequency bands above 200 MHz, a quadrifilar helical antenna having an elongate dielectric core with a relative dielectric constant greater than 5 has a conductive sleeve surrounding a proximal part of the core and a longitudinal feeder structure extending through the core to a connection with the helical antenna elements at a distal end of the core. The antenna is operated in an upper frequency band in which it exhibits a first mode of resonance characterized by current maxima at the connections of the helical elements to the feeder structure and at their junctions with the rim of the sleeve, and in a lower frequency band in which the antenna exhibits a second mode of resonance characterized by current minima in the region of the junctions of the helical elements and the sleeve rim. To permit dual mode operation, the antenna system includes an impedance-matching diplexer having filters coupled between a common port for the antenna and further ports for connection to radio signal processing equipment such as a GPS receiver and a mobile telephone operating in the two frequency bands. In the preferred embodiment, the filters and impedance matching elements are formed as microstrip elements on a single substrate.

Inventor: NEWLAND PAUL BENJAMIN
IPC: H04W52/02
Filed: 1987-02-19
Abstract: A computer-controlled cordless telephone system having a base unit and a handset unit provides for increased functionality in communications between the base unit and the handset unit, and also provides a controlled power-up/power-down mode of operation for the handset unit. Increased functionality is achieved by employing a message format for control signals transmitted between the base unit and the handset unit in the form of frequency shift keyed (FSK) signals which include a data field. This data field may be in the form of either opcode data or digit data, thereby allowing for many different commands or functions. Power to a computer, a receiver and certain other selected circuitry in the handset unit is controlled to minimize power consumption when the handset unit is in an out-of-cradle-and-standby state. Power to other nonessential circuitry in the handset unit is turned completely off during this state. The handset unit automatically turns on to a full operating mode from the alternating power-up/power-down mode in response to events such as (1) a user depressing a key no the keypad of the handset unit for either initiating a telephone calls or paging the base unit, and (2) the base unit detecting an incoming ringing signal on the telephone lines.
