Abstract
This paper presents a resonant cavity antenna (RCA) with a directive tilted beam at 28 GHz. A cylindrical waveguide fed by a coaxial probe is used as the main radiator to make a tilted beam. Besides, a proper single-layer partially reflective surface (PRS) is used to enhance the performance of the RCA structure in terms of making a directive pencil beam. A tilted beam at the angle of θ = 30 0 with a high gain feature is achieved over the desired bandwidth from 27.8 GHz to 28.5 GHz. The maximum gain is 15.8 dBi at 28 GHz. The proposed antenna is suitable for the millimeter wave wireless communications, radar systems and tracking technologies.
