| Research Abstract |
We have discussed a double-layer waveguide-type planar antenna with a corporate-feedcircuit on the bottom layer and a radiating slot array on the top layer in the 300GHzband. 16x16-element arrays have been fabricated by diffusion bonding of laminated thincupper plates. A high antenna efficiency of about 75% has been achieved at the peak inan antenna by decreasing all the parameters by 10um. The maximum available transmissionrate is estimated to be about 17Gbps by obtaining 10GHz bandwidth of the center frequencyfor bit-error-rate less than 10E-10 in an experiment with 50cm distance and 20uWtransmission power.
