| description | To date, few broadband DRAs can cover n257, n258, n260, and n261 bands with a small physical footprint (e.g., < <inline-formula> <tex-math notation="LaTeX">$0.4\lambda _{0}\times 0.4\lambda _{0}\times 0.15\lambda _{0}$ </tex-math></inline-formula>, where <inline-formula> <tex-math notation="LaTeX">$\lambda _{0}$ </tex-math></inline-formula> is the free-space wavelength at 28GHz). This article proposes a compact and broadband substrate-integrated dielectric resonator antenna (SIDRA) suitable for 5G millimeter-wave band applications. Four operating modes from three resonators, including TE111 and TE131 modes from the DR, slot mode from the H-shaped feeding slot, and patch mode from the inserted ring patch, are excited to achieve a bandwidth of 61.9% (24-45.5 GHz) with a compact size of <inline-formula> <tex-math notation="LaTeX">$0.37{\lambda }_{0}\times 0.37{\lambda }_{0}\times 0.125{\lambda }_{0}$ </tex-math></inline-formula>. The proposed DRA can be extended to an array with <inline-formula> <tex-math notation="LaTeX">$\sim 0.5 \lambda _{0}$ </tex-math></inline-formula> element interval to obtain wide-angle beam scanning capability. A <inline-formula> <tex-math notation="LaTeX">$1\times 4$ </tex-math></inline-formula> SIDRA array was simulated, achieving beam-scanning area of ±45° and ±32° at the frequencies of 28/39 GHz. Further, the DRA array was fabricated and tested. It offers a measured 10-dB bandwidth (|S11| ≤ −10 dB) of ~60.4% (23.5-43.7 GHz), in which the gain varies between 10.1 to 12.5 dBi. |
