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

本文讨论了一种双层波导型平面天线，该天线在300ghz波段的底层采用公司馈电电路，顶层采用辐射槽阵。采用扩散键合的方法制备了16x16元阵列。通过将所有参数降低10um，在天线峰值处获得了高达75%的天线效率。在距离为50cm，发射功率为20uw的实验条件下，在误码率小于10E-10的情况下，获得中心频率的10GHz带宽，估计最大可用传输速率约为17Gbps。

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.
