Abstract :
A multi-step Ka/Ka dichroic plate (Frequency Selective Surface (FSS)) is designed, manufactured and tested for use in NASA´s Deep Space Network (DSN) 34m Beam Waveguide (BWG) antennas. The proposed design allows ease of manufacturing and ability to handle the increased transmit power (reflected off the FSS) of the DSN BWG antennas from 20kW to 100 kW. The dichroic is designed using HFSS and results agree well with measured data considering the manufacturing tolerances that could be achieved on the dichroic.
