Abstract

A wideband dielectric resonator antenna is proposed in this paper. To enhance the bandwidth, two stacked resonators with different dielectric constants and sizes are used, and a coaxial probe is placed off the antenna axis to excite the HEM_11delta mode in the DRA. The effects of antenna parameters such as dielectric constant, probe length and excitation position as well as air-gaps are investigated. The analysis is performed numerically, using commercial software high frequency structure simulator. An impedance bandwidth as wide as 63% (from 6.9 GHz to 13.2 GHz, VSWR les2) is achieved with the proposed antenna
