Abstract

A 1 × 2 multiple-input multiple-output (MIMO) antenna with super-ultra wideband (super-UWB) operation and high isolation is proposed. The antenna element has an eye-shape radiator fed by a tapered shape feedline on the top side and a defected ground structure etched on the bottom ground plane. A high isolation between two radiators is achieved by introducing a T-shape and two small arm shape stubs at the center of the ground plane. The proposed design was verified by a fabricated prototype and measurement. The measured results show that the MIMO antenna achieves impedance bandwidth of 3 ~ 45 GHz, isolation of 21 dB, and a peak gain of 10.1 dBi. The envelope correlation coefficient is less than 0.02. The overall size of the design is only 0.26λ0L × 0.3λ0L (λ0L is the free space wavelength at 3 GHz).
