摘要：
This paper presents three different D-Band (110 - 170 GHz) phase shifters for high-bandwidth communication and radar applications. The proposed phase shifters offer phase shifts of 180 degrees, 90 degrees and 45 degrees and show only very little amplitude- and phase-error over the full D-Band. Furthermore based on the measurement results of the individual phase shifters the group factor of an eight element phased array system was calculated. The results were used to verify the suitability of such phase shifters as feeding elements in phased array systems. It is shown that these phase shifters are a good choice for high bandwidth systems and offer bandwidths between 25 and 50 GHz, depending on the maximum required tilt angle of the array.
