Abstract

In this paper, we present the design of a cylindrical conformal transmitarray antenna for generating high-gain beam. A low-profile transmitted element with 3-bit quantization is designed. It can cover 360˚ transmission phase shift range with transmission magnitude below -2 dB. A prototype of the cylindrical conformal transmitarray antenna is fabricated and measured. The measured gain is 21.75 dBi with aperture efficiency of 42.7%, and the thickness of the transmitarray is only 0.1 wavelengths at operating frequency.
