Abstract

The invention discloses a circularly polarized positioning antenna and wearable equipment. The circularly polarized positioning antenna comprises a first annular radiator working in a first frequencyband, a first branch knot which is in coupling connection with the first annular radiator and is used for accessing a first feed signal so as to excite the first annular radiator to work in a first radiation mode, and a second branch knot which is in coupling connection with the first annular radiator; a preset distance is formed between the second branch knot and the first branch knot; the secondbranch knot is used for grounding or used for accessing a second feed signal; the two radiation modes have the same amplitude and 90-degree phase difference, namely the annular radiator generates right-handed circular polarization radiation. Therefore, the positioning antenna can better receive navigation satellite signals, and right-handed circular polarization radiation generated by the annularradiator can also filter left-handed circular polarization navigation satellite signals reflected by a high-rise building or the ground to reduce multipath interference, thereby effectively improvingthe positioning precision of the positioning antenna of the wearable equipment.

Description

technical field [0001] The present application belongs to the technical field of antennas, and in particular relates to a circular polarization positioning antenna and a wearable device. Background technique [0002] In the field of smart watches or bracelets, positioning accuracy has always been a pain point that people pay attention to. Traditional positioning antennas for smart watches or bracelets are mostly linearly polarized antennas, but the signals sent by navigation satellites are right-handed circularly polarized signals after passing through the ionosphere, so the positioning antennas of smart watches or bracelets cannot receive all signals from navigation satellites , and the navigation satellite signal is reflected by the ground, tall buildings, trees and other odd times, it will become a left-hand circularly polarized signal, and the multipath interference will seriously affect the positioning effect of the whole machine.
