Abstract

This paper investigates a wideband cylindrical transparent dielectric resonator antenna (DRA), working as a light cover. The antenna is made of transparent materials. To broaden its bandwidth, two layers of transparent materials with different dielectric constants are put together. The lower layer has a hollow region for the accommodation of an LED light source. The VSWR, radiation pattern, and antenna gain are simulated and measured. Results show that it can simultaneously work as an antenna and a light cover, with negligible effects of the LED light source on the antenna performance.
