This paper presents a broadband and wide-beam magnetoelectric dipole antenna operating in the Ka-band. The antenna is based on a stacked structure of multilayer dielectric substrates and semi-cured layers. By adding parasitic elements around the radiating patches, the beamwidth is broadened, while parasitic capacitance is introduced to extend the antenna bandwidth. The antenna structure is simulated, designed, and optimized with the 3D full-wave electromagnetic simulation software HFSS. The optimized simulation results demonstrate that the antenna exhibits excellent broadband performance and wide-beam characteristics, with an absolute impedance bandwidth of 22.9-46.6 GHz and a relative impedance bandwidth exceeding 68%. When operating above 24 GHz, the beamwidth exceeds 120 . The antenna\'s broadband and wide-beam properties make it suitable for broadband communication systems and wide-angle scanning applications. 关键词
