Abstract
The invention relates to an antenna soft switching system of an Angle of Departure, AoD, direction finding transmitter unit. The soft switching system comprises: a timing unit for obtaining at least a starting time of a switching event, a switching network arranged on a radio frequency, RF, signal path between an RF port and a first antenna port and a second antenna port, and a generator unit for generating at least one waveform for controlling the switching network. The generator unit is configured to control the switching network so that the amplitude of the RF signal is switched substantially smoothly from the first antenna port to the second antenna port so that level of unwanted emissions of a transmitted RF spectrum of the AoD directional finding transmitter unit are reduced. The invention relates also to an AoD direction finding transmitter unit comprising the antenna soft switching system and to an antenna soft switching method for an AoD directional finding transmitter unit.
