Wireless signal arcs rising above a dot inside a circular badge
About the Signal black outline icon
Three curved bands fan out above a small filled dot, each arc wider than the one below, forming the standard wireless broadcast shape, all held inside a thin circular frame. It communicates connectivity, reception strength, hotspots and data transmission. Use it in router setup flows, connection status bars, cafe and hotel amenity lists, IoT dashboards and telecom marketing pages.
Arc spacing stays consistent so signal strength reads at a glance, and the enclosing ring turns it into a ready-made button or badge. It pairs with router, antenna and bluetooth icons. Keep it above 20 px, or the tightest inner arc merges with the dot.
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.
