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 path with the RF pin selector and define the copper shape with pcbPath.

export default () => (
  <board width="10mm" height="10mm">
    <chip name="U1" footprint="qfn32" />
    <trace
      path={[".U1 > .pin1"]}
      pcbPath={[
        { x: -3.5, y: 1.75 },
        { x: -3.5, y: 2.5 },
        { x: -4, y: 2.5 },
      ]}
    />
  </board>
)

The pcbPath points are PCB coordinates in millimeters. Add more points to draw a longer antenna shape, a board-edge launch, or a meandered RF trace.

caution

This controls the antenna geometry in tscircuit, but it does not calculate RF performance. For a production WiFi antenna, tune the dimensions, trace width, clearance, stackup, and ground keepout for your target frequency and PCB manufacturer.
