1. A zero-clearance fifth-generation (5G) ultra-wideband (UWB) Multiple-Input Multiple-Output (MIMO) antenna, comprising a main dielectric substrate, lateral dielectric substrates, and multiple antenna elements, wherein
the lateral dielectric substrates are arranged at two sides of the main dielectric substrate;
the multiple antenna elements are arranged on the lateral dielectric substrates;
each of the multiple antenna elements comprises a feeding element and a grounding radiator element, and wherein, for each of the multiple antenna elements:
the feeding element is provided at an inner side of each of the lateral dielectric substrates; and the grounding radiator element is provided at an outer side of the lateral dielectric substrate;
the feeding element is connected to a feeding line on the main dielectric substrate, and comprises a first vertical branch, a second vertical branch and a horizontal branch;
the first vertical branch comprises a top end connected to one end of the horizontal branch, and a bottom end connected to the feeding line; and
the second vertical branch comprises a top end connected to another end of the horizontal branch, and a bottom end spaced apart from the main dielectric substrate.
