Embodiment 1
[0045]In the health monitoring smart watch provided with a positioning device described in this embodiment, the communication antenna includes a circular first PCB substrate K1, a second PCB substrate N1, and a third PCB substrate M1; the first to The third PCB substrate M1 has the same size, and an arc-shaped notch K11 is provided on both sides of the three, and a microstrip shielding layer K12 is provided at the arc-shaped notch K11; a first microstrip antenna is provided on the first PCB substrate K1 ; The first microstrip antenna includes a first ring arm K21, a second ring arm K22, a third ring arm K23; the first ring arm K21, the second ring arm K22, the third ring arm The three ring arms K23 are set concentrically; if the vertical direction passing through the center of the circle is the Y axis, and the horizontal direction is the X axis, the first ring arm K21 is provided with a fan-shaped gap in the area of an angle of 122° to 132° counterclockwise from the Y axis Q...
Embodiment 2
[0049] In the health monitoring smart watch provided with a positioning device described in this embodiment, the radial width of the outer ring and the inner ring of the first circular ring arm K21 is 0.8cm-1.2cm; the second circular ring The radial width of the outer ring and the inner ring of the arm K22 is 0.4cm-6cm; the radial width of the outer ring and the inner ring of the third ring arm K23 is 0.4cm-0.6cm. Wherein, the radial width of the outer ring and the inner ring of the second ring arm K22 is the same as the radial width of the outer ring and the inner ring of the third ring arm K23. Wherein, the radial width of the outer ring and the inner ring of the first ring arm K21 is 1 cm. Wherein, the radial width of the outer ring and the inner ring of the third ring arm K23 is 0.5 cm.
[0050] The above parameters are obtained through continuous testing and adjustment. They are the most stable and best performance specific parameters. The specific actual test results ar...
