- Abstract
- Gap-coupled unidirectional dielectric radiator (UDR) is proposed in this paper. Especially, multi-pole gap-coupled UDR is employed to obtain broadband characteristic. Design parameters of UDR such as length of resonator and distance of gap are determined using an equivalent circuit model of an evanescent nonradiative dielectric (NRD) guide. The proposed UDR has advantages of planar integration due to good union between antenna and NRD guide, simple structure, easy design procedure, and low cost. Prototypes of gap-coupled UDR are designed and measured around 38GHz. The measured result shows a good agreement with simulation data.
