The stacked structure of an aperture‐coupled cylindrical dielectric resonator (DR) antenna is studied experimentally. The effects of the offset and the air gap between the driven and parasitic DR elements are investigated. It is found that the bandwidth of the stacked structure can increase from the single‐element value of 9% to 37%. The voltage standing‐wave ratio, the radiation patterns, and the antenna gain are also reported. © 1997 John Wiley & Sons, Inc. Microwave Opt Technol Lett 14: 215–217, 1997.
