ABSTRACT This paper presents a novel two-element multiple input multiple output (MIMO) reconfigurable antenna that can be switched among 600 MHz, 1.8, 2.4, 3.5, and 5.5 GHz bands. The proposed antenna consists of two semi-circular ring-shaped strip-lines and a rectangular slot on the top conducting layer of the substrate and a U-shaped slot, etched on the bottom side of the substrate. Frequency reconfigurable characteristics have been achieved using single pole four throw radio frequency micro-electro-mechanical system switch. The switch has been installed in the ground slot. The dimensions of the proposed MIMO antenna are 32 × 98 × 1 mm3. Measured isolation greater than 15 dB has been achieved in the operating bands. The calculated envelop correlation coefficient is less than 0.04 and the diversity gain in the operating bands is greater than 9.8 dB.
