Abstract :
A CMOS transmission line-to-waveguide transitions with a patch antenna for a WR3 waveguide (220-325 GHz) was designed using an electromagnetic-field simulator. The position of inserting the antenna to the waveguide and the size of the antenna were optimized to realize a low insertion loss and a wide bandwidth. As a result, an insertion loss of 0.9 dB and a 3-dB bandwidth of 120GHz were achieved.
