  • Method and system for forming an antenna pattern
    Patent number: 6784836
    Abstract: In an electronic circuit for forming an antenna pattern, the antenna signals having the required phase shift are generated by means of two phase-locked loops which have a common reference signal. A control current, which is added at the output node of the charge pump 26 and/or 27, is used to control the phase shift of the antenna signals. This allows the implementation of the phase shift operation in the analog domain, which decreases the cost of a corresponding consumer device, such as a car-radio or a mobile communication system.
