Title:
SINGLE-FREQUENCY CIRCULAR POLARIZATION POSITIONING ANTENNA AND WEARABLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/238217
Kind Code:
A1
Abstract:
The present application discloses a single-frequency circular polarization positioning antenna and a wearable device. The single-frequency circular polarization positioning antenna comprises: an inverted F antenna (11) and a parasitic antenna (12), which are orthogonally arranged. By means of feeding the inverted F antenna (11), resonance is generated on the parasitic antenna (12) via a coupling effect, thereby simplifying the overall structure of the circular polarization antenna, so that same can be more easily implemented on a wearable product, such that the positioning antenna can better receive navigation satellite signals. In addition, right-hand circular polarization radiation generated by an annular radiator can also filter left-hand circular polarization navigation satellite signals reflected by a tall building or the ground, so as to reduce multipath interference, thereby effectively improving the positioning precision of the positioning antenna of the wearable device.
