Abstract
The stacked structure of an aperture-coupled cylindrical dielectric re sonator (DR) antenna is studied experimentally. The effects of the off set and the air gap between the driven and parasitic DR elements ale i nvestigated. It is found that the bandwidth of the stacked structure c an increase fr om the single-element value of 9% to 37%. The voltage s tanding-wave ratio the radiation patterns, and the antenna gain are al so reported. (C) 1997 John Wiley & Sons, Inc.
