Abstract

This communication introduces a new structure of a partially reflective surface (PRS) to realize gain enhancement for a millimeter-wave Fabry-Pérot Cavity (FPC) antenna. It is the first attempt at applying a Fresnel zone plate (FZP) to a single-layer PRS, which contributes to a significant gain improvement. The proposed antenna consists of a feeding source, a substrate-integrated quasi-curve reflector, and the proposed PRS. With the quasi-curve reflector, multiple resonate modes are excited, providing a wide 3 dB gain bandwidth. For validation, a prototype of millimeter-wave FPC antenna is designed and measured. The antenna can be implemented by low-cost and mature printed-circuit-board (PCB) technology. The antenna yields a measured impedance bandwidth of 17.8% from 54 to 64.5 GHz and a 3 dB gain bandwidth of 13.3% from 56 to 64 GHz. The measured peak gain is 21 dBi at broadside direction. This antenna finds potential applications in high-speed communications at the millimeter-wave spectrum.
