The paper presents the results of a novel 3-D shared aperture 3 × 3 matrix antenna-array for 26
GHz band 5 G wireless networks. Radiation elements constituting the array are hexagonal-shaped
patches that are elevated above the common dielectric substrate by 3.35 mm and excited through
a metallic rod of 0.4 mm diameter. The rod protrudes through the substrate of 0.8 mm thickness.
It is shown that by isolating each radiating element in the array with a wall suppresses unwanted
electromagnetic (EM) wave interactions, resulting in improvement in the antenna’s impedance
matching and radiation characteristics. Moreover, the results show that by embedding hexagonalshaped slots in the patches improve the antenna’s gain and radiation efficiency performance. The
subwavelength length slots in the patches essentially transform the radiating elements to exhibit
metasurface characteristics when the array is illuminated by EM-waves. The proposed array
structure has an average gain and radiation efficiency of 20 dBi and 93%, respectively, across
24.0–28.4 GHz. The isolation between its radiation elements is greater than 22 dB. Compared to
the unslotted array the improvement in isolation between radiating elements is greater than 11dB, and the gain and efficiency are better than 10.5 dBi, and 25%, respectively. The compact
array has a fractional bandwidth of 16% and a form factor of 20 × 20 × 3.35 mm3. [--]
