## Abstract A broadband high‐gain single‐feed cross‐aperture coupled patch antenna is presented in this paper. The measured results confirm that the antenna is capable of a 14.4% impedance bandwidth (VSWR ≤ 2), 3% of 3‐dB axial‐ratio bandwidth, and 17.4% of gain (>8 dBic) bandwidth with a mean gain
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 dri¨en and parasitic DR elements are in¨estigated. It is found that the bandwidth of the stacked structure can increase from t
