The patent abstract shows that this invention relates to the field of antenna technology and wireless communication technology, and discloses a broadband wide-beam artificial magnetic conductor monopole antenna, including: a dielectric substrate, comprising a first copper foil layer, a first prepreg layer, a core layer, a second prepreg layer, and a second copper foil layer stacked sequentially from the top layer to the bottom layer; a second metal layer and a third metal layer are respectively arranged on the upper and lower surfaces of the core layer, and a first metal layer is arranged on the upper surface of the first prepreg layer; the radiating element is arranged on the first metal layer; the AMC structure includes an AMC region and multiple AMC vertical through-holes. The AMC region is arranged at a position of the second metal layer that is opposite to the radiating element, and the AMC region includes multiple AMC metal units arranged in a periodic array; both ends of each AMC vertical through-hole are connected to an AMC metal unit and the third metal layer. This invention designs the radiating element back-to-back with the AMC structure. After part of the electromagnetic waves are reflected by the AMC structure, coherent enhancement is formed, ensuring that |S11| is below -10 dB within the 2 GHz frequency band.
