- Abstract
- In this work, a millimeter-wave wideband wide beamwidth modified angled dipole antenna is proposed for 5G millimeter-wave(mmW) IoT applications. The modified angled dipole antenna which has a dipole arm that is bent once more perpendicular to the ground plane compared to the existing angled dipole is proposed to improve not only the beamwidth but also the S 11 bandwidth. The image current is formed in the direction perpendicular to the ground by the dipole arm bent to be orthogonal to the ground. Because only the E-field in the direction perpendicular to the ground can be formed by the boundary condition, the E-field radiated from the proposed antenna can be radiated along the ground plane, and thus the E-plane beamwidth is widened, and the H–plane beamwidth can be widened. The measured -10 dB S 11 bandwidth is 5 GHz(=17.8%) ranging from 25.7 GHz to 30.7 GHz, and the measured HPBW is 160°±5 ° and 310∘±10∘ for the E-plane and H-plane, respectively. To verify whether the proposed antenna is practically applied to 5G IoT applications, the beamforming IC was connected to the proposed antenna array, and the E-plane beam-forming radiation pattern was measured. Although it was applied only to the -90 ∘≤β≤90∘ range, the -3 dB E-plane beamwidth was 130°, ensuring wide coverage.
