In this paper, a laminated planar feed structure has been proposed to excite the omnidirectional radiation modes of a dielectric resonator (DR): TM01δ, TM011+δ and TM012+δ. The resonant frequencies of the three modes are 2.44, 2.78 and 3.10 GHz re

Ultra-wideband (UWB) technology is widely used in many communication scenarios. However, narrowband systems can easily interfere with the UWB system, which generates multipath fading. In order to solve these interferences and meet the design requirem
