Dielectric Resonator Antennas (DRA) are mostly investigated for frequencies above approx. 5GHz, but in this paper they are suggested for use in the mobile communication standard UMTS (1.92 – 2.17 GHz) base stations, because they can provide a denser aperture since they can be drastically reduced in size through proper selection of the materials dielectric constant. In this paper the main aspect will be the investigation of dual polarized resonators and the buildup of arrays. The goal is to provide a solution which can compete with the commercial market and additionally offer new with the commercial market and additionally offer new possibilities.
