this work proposes a novel design of two-layered antenna array targeting the D-Band region of the spectrum, likely to become the next commercial battleground for millimeter-wave communications. The design is basically an 8 × 8 hollow metallic cavity backed antenna array which exhibits a thin planar footprint with volume of ( 30.1 \times 26.4 \times 1.2 mm3) and it is capable of covering the 153-161 GHz, which corresponds to 5.2% of FBW. Radiation characteristics are investigated for both 2 × 2 subarray and the whole 8 × 8 antenna where the obtained peak gain values are 12.4 dBi and 22.4 dBi, respectively. The achieved HPBW is 3.5° whereas grating lobes appears at 29°. These values are in-line with the requirements of next-generation point to point communications where short links are foreseen.

Abstract

this work proposes a novel design of two-layered antenna array targeting the D-Band region of the spectrum, likely to become the next commercial battleground for millimeter-wave communications. The design is basically an 8 × 8 hollow metallic cavity backed antenna array which exhibits a thin planar footprint with volume of ( 30.1 \times 26.4 \times 1.2 mm3) and it is capable of covering the 153-161 GHz, which corresponds to 5.2% of FBW. Radiation characteristics are investigated for both 2 × 2 subarray and the whole 8 × 8 antenna where the obtained peak gain values are 12.4 dBi and 22.4 dBi, respectively. The achieved HPBW is 3.5° whereas grating lobes appears at 29°. These values are in-line with the requirements of next-generation point to point communications where short links are foreseen. Index Terms - Antenna array, backhauling communications, D-Band, millmeter-wave, metlic waveguide, slotted antenna.
