About the Signal black filled 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 solid black filled version of the signal icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
