Description
Summary:In this paper, a radiating structure composed of two hook-shaped antenna elements is proposed for millimeter waves applications operating at 26 \mathrm{GHz} .1 \times 2 antenna array that is excited by a T-junction power divider, has 12 \times 18 \mathrm{~mm}^{2} physical size. It operates with a wide bandwidth (2.75GHz) between 25.05 and 27.8GHz. The antenna array is modified to a two-element MIMO system by positioning two hook-shaped arrays at a distance of 1.5 \lambda at 26GHz. The 26GHz frequency band falls into the millimeter-wave range, and it is often used for radar applications such as automotive radar systems, weather radar, and some military radar systems. The MIMO system is designed on Rogers RT/Duroid substrate with 0.8 \mathrm{~mm} thickness. The MIMO system achieves 8.9 \mathrm{~dB} maximum gain and isolation above 35 \mathrm{~dB} at the resonance band. Low coupling between radiating elements attains a low value of \mathrm{ECC}\lt 0.0005 and high diversity gain of 10 \mathrm{~dB} within the working spectrum.
