采用扩散键合方法，在薄铜板上加入等效过刻蚀量的杂质，制作了16×16单元平板叠层波导缝隙阵列天线。在考虑等效过刻蚀量的情况下，测量的反射特性与设计的反射特性吻合较好。在设计频率下，增益达到32.6dBi，天线效率达到76.5%，增益大于31.5dBi时带宽达到19.2%。
A 16×16-element plate-laminated-waveguide slot array antenna is fabricated by diffusion bonding of thin copper plates with inclusion of equivalent over-etching amount. The measured reflection characteristic has good agreement with the design one by considering the equivalent over-etching amount. At the design frequency, 32.6-dBi gain, 76.5% antenna efficiency and 19.2% bandwidth for gain more than 31.5 dBi have been achieved.
