Electronic tag suitable for liquid and human body surface

The utility model discloses an electronic tag suitable for liquid and human body surface, which comprises a tag body arranged on a base material, the tag body comprises a peripheral antenna, a basic antenna and a chip connected with the basic antenna, the periphery of the basic antenna is provided with four metal pole plates, and the metal pole plates are arranged on the periphery of the basic antenna. And the peripheral antenna comprises a four-oscillator petal-shaped antenna which is coupled with the four metal polar plates to form polar plate capacitance. According to the utility model, a brand new antenna shape is adopted, a traditional folded dipole form is abandoned, the four-dipole petal-shaped antenna and liquid or a human body surface form a capacitor, and the liquid or the human body surface is used as a part of extension of the antenna, so that the requirement of a common liquid label with a reading distance of more than 3 meters on the liquid or the human body surface is met. 本实用新型公开了一种适用于液体与人体表面的
