Title:
CIRCULARLY POLARIZED ANTENNA AND WEARABLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/068583
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of smart wearable devices, and provides a circularly polarized antenna and a wearable device. The circularly polarized antenna is applied to a wearable device, and the antenna comprises: an annular slot structure comprising an annular metal radiator, the effective perimeter of the radiator being equal to the wavelength corresponding to the central working frequency of the circularly polarized antenna; a feed terminal connected across the slot structure, one end of the feeder terminal being electrically connected to the radiator, and the other end being connected to a feed module of a motherboard of the wearable device; at least one first grounding terminal connected across the slot structure, one end of the first grounding terminal being electrically connected to the radiator, and the other end being electrically connected to a grounding module of the motherboard by means of an inductor. The circularly polarized antenna of the present disclosure can realize circular polarization of wearable devices of different sizes and is simple in structure, and the application adaptability and flexibility can also be improved while greatly simplifying the structure and design cost of the circularly polarized antenna.
