Compact dielectric resonator antenna for PCS mobile handsets

In response to increasing demand for compact efficient antennas, various cylindrical geometries of dielectric resonator antennas (DRA) are investigated in this paper. These DRA geometries offer significant reduction in volume, making them potential candidates for use in compact applications such as mobile communication handset. Approximate theory of PMC walls developed for predicting resonant radiation frequency of different DRA geometries, gives good agreement with available experimental results. Volume minimization for compact DRA designs is also discussed and a design is proposed for a mobile telephone handset, suitable for the GSM 900 system.
