Abstract :
A novel dielectric resonator antenna with an ultra-wideband (UWB) bandwidth and great time-domain performances has been proposed. The proposed feed for cone dielectric resonator antenna is a circular patch, which has the potential to achieve ultra-wideband characteristic. The operating frequency range of the antenna is 2.77-11.63GHz. The design provides constant group delay, consistent omni-directional characteristics and high efficiency. The overall dimension of the proposed antenna is 24.3mm × 32.6mm with 6.08mm thickness. The proposed antenna provides the valuable dielectric resonator antenna design and shows great value in the fields of breast cancer detection systems.
