Draw a WiFi Antenna

Use a manual trace path when you want to draw open-ended copper from an RF pin, such as a simple WiFi antenna or antenna feed. Instead of using from and to, provide a pcbPath with the RF pin selector and define the copper shape with pcbPath.

export default () => (
  <board width="32mm" height="16mm">
    <chip name="U1" footprint="qfn32" />
    <trace
      path={[".U1 > .pin1"]}
      width="0.3mm"
      pcbPath={[
        ".U1 > .pin1",
        { x: -2.5, y: 4.2 },
        { x: 4.0, y: 4.2 },
        { x: 4.0, y: 6.6 },
        { x: 15.0, y: 6.6 },
        { x: 15.0, y: 5.2 },
        { x: 6.0, y: 5.2 },
        { x: 6.0, y: 3.8 },
        { x: 15.0, y: 3.8 },
        { x: 15.0, y: 2.4 },
        { x: 6.0, y: 2.4 },
        { x: 6.0, y: 1.0 },
        { x: 15.0, y: 1.0 },
      ]}
    />
  </board>
)

The pcbPath points are PCB coordinates in millimeters. This example draws a meandered printed antenna near the board edge. Adjust the points to change the overall length, spacing between runs, and feed location.
