Provided is a wireless charging loop antenna. The wireless charging loop antenna includes an extracorporal planar loop antenna and an intracorporal planar loop antenna. The intracorporal planar loop antenna is disposed inside a body, and the extracorporal planar loop antenna is disposed on a skin outside the body. The extracorporal planar loop antenna includes an extracorporal antenna substrate, an extracorporal loop radiation patch, paired connection radiation patches and a patch capacitor. The extracorporal loop radiation patch is provided with at least one extracorporal radiation patch gap. The patch capacitor is disposed at one of the at least one extracorporal radiation patch gap. The extracorporal loop radiation patch and the paired connection radiation patches form a circuit. The extracorporal loop radiation patch, the paired connection radiation patches and the patch capacitor are all on a same surface of the extracorporal antenna substrate.
