Abstract
In order to design a circular polarization antenna for handhold electronic products, a cylindrical dielectric resonator with tapered rod is investigated. The antenna is fed by a truncated square patch to obtain high gain and wide band, and the top of it is with slide-down instead of flat surface to radiate along with the central axis. In addition, to analyze the antenna efficiently, three dimensional Maxwell equations are solved by using an alternating-direction implicit scheme combining with the pseudo-spectral time-domain method. This algorithm allows for an accurate treatment of curved geometries with higher efficiency. Numerical results show an excellent agreement with experiments for the fabricated antenna operated around 60 GHz.
