Abstract:A dielectric resonator antenna (DRA) is proposed for dual-band resonance for the mid-band (sub-6 GHz) and the high-band (mm-wave) 5G applications. The proposed composite DRA consists of an annular dielectric radiator concentrically integrated with a high-permittivity cylindrical DRA to realize resonance at two distinct frequencies with large frequency ratio. The impact of composition of two distinct dielectric materials on the radiation in both bands is analyzed taking into account the effective permittivity o… Show more
