description The utility model provides an antenna structure and terminal equipment, the antenna structure comprises a loop antenna, the loop antenna comprises a feeding point and a grounding point, and a switch tuning circuit is connected with the grounding point; the switch tuning circuit is disconnected, the grounding point is disconnected from the ground end, and the loop antenna as a radiator receives and transmits electromagnetic waves of a first frequency band; wherein a first wavelength corresponding to the first frequency band is a quarter of a preset wavelength, and the preset wavelength is set to be a wavelength corresponding to an electromagnetic wave radiated by the natural length of the loop antenna. The switch tuning circuit is arranged, when the switch tuning circuit is disconnected, the grounding point is disconnected from the ground end, the wavelength corresponding to the electromagnetic wave of the first frequency band radiated by the loop antenna is one fourth of the preset wavelength, the one fourth
