【Abstract】 A kind of transmission millimeter wave antenna of Fresnel zone plates with continuous phase structure was designed and fabricated with the principle of diffraction optics. This kind of antenna has the features of light weight, small volume, high gain and low cost. Measurements and simulation calculation and analysis were carried out on the antenna. The result of calculation agrees well with the measurement.更多还原
