Abstract :
We investigate circular sector and annular sector dielectric resonator antenna (DRA) geometries. The advantage these geometries offer, compared to conventional circular cylindrical DRAs are significant reductions in volume, making them potential candidates for use in compact applications such as mobile communication handsets. Approximate theory, simulation, and experimental results are provided to support the findings. In particular, a sector DRA is demonstrated to have 75% less volume than a conventional cylindrical DRA, with the same resonant frequency. The DRA volume minimization for compact antenna design is also discussed and a design is proposed and tested for a mobile telephone handset suitable for the DCS1800 system
