High-gain,High-efficiency and Wide-band Planar Antennas usingPlate-laminated Hollow Waveguides in the 300GHz Band

本文讨论了一种300 GHz频段的双层波导平面天线，其底层为共馈电路，顶层为辐射缝隙阵。用扩散连接的方法制备了16 × 16单元的叠层薄板阵列。在天线的峰值处，通过将所有参数降低10 μ m，获得了约75%的高天线效率。在50 cm距离和20 μ W发射功率下，当误码率小于10 E-10时，中心频率带宽为10 GHz时，最大可用传输速率约为17 Gbps。

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.
