Two-dimensional cavity-backed angled-dipole array antenna for 28-GHz band
This paper presents a high-gain low-sidelobe two-dimensional cavity-backed angled-dipole array antenna with 64 antennas in an 8 × 8 square grid for 28-GHz applications. This antenna yields broadband characteristics and similar 3-dB beamwidths in the E- and H-planes, and it is chosen for stable operation in a two-dimensional array environment. A nonuniform power distribution is used to excite the array to achieve a low sidelobe level (SLL) in the azimuth planes. The proposed array showed similar scanning performance in the E-and H-planes. It achieved gain exceeding 20.0 dBi and SLL below −18.5 dB for scanning angles up to 40°.
