Abstract :
This paper investigates an ultra broadband planar antenna which is appilcable in D-band systems. The proposed design allows the fabrication of the antenna on a 25μm thin flexible polyimide based substrate which is machined by standard thick film processes. The relative bandwidth of the antenna is about 36 %, a high gain from 7 to 11 dB is achieved in the frequency range from 110 - 170 GHz. The constant broadside radiation patterns are presented by measurement results and are finally compared to the simulation.
