Dual-frequency button antenna capable of being applied to body area network communication and integrated into clothes

The invention discloses a dual-frequency button antenna capable of being applied to body area network communication and integrated into clothes. The dual-frequency button antenna comprises a feeding portion, a metal supporting base and a radiator, and is characterized in that the metal supporting base is fixed on the clothes, the radiator forms the body of a button, the metal supporting base is connected with the radiator through the feeding portion, the radiator comprises a dielectric substrate, the upper surface of the dielectric substrate comprises an annular microstrip branch with one end being short-circuited and the other end being open-circuited and a rectangular microstrip branch connected with an inner ring of the annular microstrip branch, the other end of the rectangular microstrip branch is short-circuited, and the rectangular microstrip branch is located at a central position of the dielectric substrate; and the lower surface of the dielectric substrate comprises a circular ring, and the circular ring is in physical contact with the metal supporting base. The dual-frequency button antenna disclosed by the invention has robustness when operating at the human body surface, and is applicable to body area network communication scenes such as the body surface and the external body and wearable wireless electronic equipment.
