A stacked rectangular dielectric resonator antenna (DRA) is studied experimentally. The achieved impedance bandwidth of two DR stacked antenna is about 73%. By stacking two different permittivity DRs, the multi‐band of single element DRA is changed to single wideband giving out improvement in bandwidth. The antenna parameters like radiation patterns and return loss are measured and presented. These antennas may provide applications in which large bandwidth is needed. © 2010 Wiley Periodicals, Inc.
