Abstract
This paper presents a stair-shaped dielectric rod antenna, which is a simplified version of the conventional tapered rod antenna. The operation frequency is set to be 28 GHz for 5G communications. The antenna configuration is composed of three sections: a transition section from a rectangular waveguide to a circular waveguide, a horn exciter section, and a stair-shaped dielectric rod section. The number of stairs is chosen to be three. The analysis shows that the optimized rod radius and length realize a high gain of more than 22 dBi. The 3-dB beam width is approximately 15°. The VSWR is less than 2 across a frequency range of 26.5 GHz to 32 GHz.
