Antennas allow devices to send and receive digital signals such as cellular, Bluetooth, and Wi-Fi. Antennas vary greatly from device to device, but there are two major antenna designs.
The first commonly features black/white antenna cables that plug into a wireless card.
The second is generally a flat piece of plastic that looks like a sticker. With this design, the entire piece acts as an antenna.
