Abstract

The invention discloses a circularly polarized positioning antenna and wearable equipment. The circularly polarized positioning antenna comprises a feed branch knot, a first feed arm and a second feedarm, wherein the first feed arm and the second feed arm form an angle; a first radiation arm is coupled with the first feed arm, the first radiation arm is arranged in a first clearance area extending in the arrangement direction of the first feed arm in a bent mode, and the first clearance area is located on one side of the first feed arm; a second radiation arm is coupled with the second feed arm, and the second radiation arm is arranged in a second clearance area extending along the arrangement direction of the second feed arm in a bending manner; the electric signals on the first radiation arm and the second radiation arm meet the conditions that the amplitudes are equal and the phase difference is 90 degrees, and circular polarization radiation is realized, so that multipath interference is reduced, and the positioning precision of the positioning antenna of the wearable equipment is effectively improved; and the antenna is arranged in the clearance areas in a bending mode, so that the size of the whole antenna can be reduced, miniaturization is facilitated, and the antenna can be achieved on a wearable product more easily.

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. [0003] Moreover, traditional circula...
