摘要：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 whichhave a common reference signal. A control current, which is added at the output node ofthe charge pump and/or , is used to control the phase shift of the antenna signals. Thisallows the implementation of the phase shift operation in the analog domain, whichdecreases the cost of a corresponding consumer device, such as a car-radio or a mobilecommunication system.
