Hook-shaped Dual Element MIMO Antenna for X-band and Ku-band Applications

This paper proposes a simple hook-shaped MIMO antenna for X-and Ku-band applications. The MIMO comprises a hook-shaped patch with a rotated C-shaped parasitic element and a ground with a Crecent-shaped slot. It is etched on both sides of an FR4 material, having a permittivity of 4.3. The numerical results reveal that the single element of the studied MIMO with an overall size of 14×16 mm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> achieved dual operating bands of 9.77 - 11.28 GHz and 11.92 - 12.95 GHz. Antiparallel placement of the two single elements forms the anticipated MIMO and can retain the dual working bands for X- and Ku-bands. The isolation between the elements of the MIMO is greater than 20dB with good efficiency and gain, which perfectly fits with X-band and Ku-band applications.
