About the Signal black outline icon
Five nested arcs fan upward, growing from a short curve at the base to a wide sweep across the top, each one longer than the last. The rising stack is the universal picture of signal strength and wireless broadcast. Use it for wifi status bars, router setup screens, network settings, radio and streaming apps, IoT device dashboards and coverage maps.
Even spacing between the arcs keeps the fan readable, and leaving out the origin dot gives it a lighter, more open look than a standard wifi mark. Pair it with router, antenna and cloud icons; animating the arcs in sequence makes a natural connecting state.
This is the black outline version of the signal icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
