ANTENNA FOR A RADIO-FREQUENCY SYSTEM FOR EXHAUST GAS AFTERTREATMENT FOR A MOTOR VEHICLE, RADIO-FREQUENCY SYSTEM AND METHOD FOR OPERATING SAID ANTENNA

摘要

An antenna for a radio-frequency system (200) for exhaust gas aftertreatment for a motor vehicle comprises: – an antenna element (119) for transmitting and/or receiving microwaves (103), wherein – the antenna element (119) is able to be electrically coupled to a radio-frequency exciter (201) in order to transmit and/or receive the microwaves (103) in a first operating state, and – the antenna element (119) is able to be electrically coupled to a heating controller (202) in order to apply an electrical voltage for heating to the antenna element in a second operating state, in order thereby to remove deposits on said antenna element.
