Novel slot‐fed dielectric resonator antenna is studied experimentally. The antenna is comprised of a rectangular dielectric resonator and a mictrostrip fed coupling slot. The multiband resonances of the two radiators i.e., slot and dielectric resonator are combined to extend the antenna bandwidth. Dielectric resonator of three different thicknesses is studied, providing a bandwidth of 49.25%. The radiation patterns are measured and are presented. © 2009 Wiley Periodicals, Inc.
