A low-profile transmitarray lens design is presented at X-band, which is composed of only one layer of substrate with thickness of 0.13 free-space wavelengths. The transmitted unit cell utilises structure of two metallic layers and four via holes, broadening the transmitted phase shift range to more than 310° while transmission magnitude is within −3 dB under normal incidence. A prototype of the transmitarray lens with aperture size of 280 mm is designed, simulated and measured. Measurement and simulation results agree well with each other and gain of 23.9 dBi is obtained at 10 GHz; the proposed low-profile transmitarray lens antenna could be applied to practical X-band radar systems with low cost and convenience.
