Claim 0:
1. An antenna soft switching system of an Angle of Departure, AoD, direction finding transmitter unit, wherein the antenna soft switching system is arranged between at least one radio frequency, RF, transmitter module and at least one antenna array, the soft switching system comprises:
a timing unit for obtaining at least a starting time of a switching event,
a switching network arranged on an 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,
wherein the generator unit is configured to reduce a level of unwanted emissions of a transmitted RF spectrum of the AoD direction finding transmitter unit by controlling the switching network so that the amplitude of the RF signal is switched smoothly from the first antenna port to the second antenna port.
