摘要：
This letter proposes a novel high gain, high efficiency optically transparent Fabry-Perot Cavity antenna operating in millimetre-wave. The antenna employs dual layers of transparent partially reflective surface and a transparent artificial magnetic conductor structure to enhance the gain and gain bandwidth. The reflection amplitude and phase have a low sensitivity to the sheet resistance of the transparent materials, which greatly reduce the requirement for the conductivity of transparent material and simplify the manufacturing process. The size of the antenna is 3.47 lambda 0 x 3.47 lambda 0 x 0.68 lambda 0. A peak gain of 14.2 dBi, peak radiation efficiency of 67.1% and optical transparency of 81% are achieved. A novel high gain, high efficiency optically transparent Fabry-Perot Cavity antenna operating in millimetre-wave is proposed. The antenna employs dual layers of transparent reflective surfaces and a transparent electromagnetic band gap ground to enhance the work band and obtain a high gain radiation. The reflection amplitude and phase have a low sensitivity to the sheet resistance of the transparent materials, which greatly reduce the requirement for the conductivity of transparent material and simplify the manufacturing process. image
