In this paper, a microstrip line fed
windmill shaped antenna for superwideband multiple input multiple output (MIMO)
applications at terahertz frequency spectrum is proposed. It comprises a second
iterative fractal radiator, tapered microstrip line feeding and partial
rectangular ground plane. The antenna element and MIMO configurations are
operating from 3.1 THz to more than 60 THz. The footprint of spatial and
pattern diversity configurations are 110 μm×125 μm and 110 μm×155 μm
respectively. Both configurations have isolation more than 30 dB in maximum
part of their operating frequency spectrum along with distorted omnidirectional
radiation patterns and acceptable values of MIMO performance parameters.
