Abstract
A two-port multiple input multiple output (MIMO) dielectric resonator antenna is proposed where two orthogonally connected feed lines are combined to unite two orthogonally produced modes. The feed lines build a hybrid network. The backplane is defected by a circular defected ground structure (CDGS), which is extended by two rectangular slits placed orthogonally with the input ports. The antenna uses a single ‘H/I’-shaped dielectric resonator (DR) element. It covers frequency spectrum from 7.29 to 10.65 GHz and fulfils the international telecommunication union (ITU) (8–8.5 GHz) and Maritime Radio Navigational (8.85–9 and 9.2–9.5 GHz) application bands. The antenna offers very high port isolation (>18 dB) and diversity properties throughout the whole application band. The antenna also provides circular polarization (AR ≤ 3 dB) in the operating ranges from 8 to 8.25 GHz and 8.85 to 8.9 GHz. Simulated and measured results make clear to the antenna most suitable for MIMO operation.
