All radios (including those that do wifi stuff inside of televisions) need an antenna in order to perform wireless communications. An antenna may be obvious and external (like one on the fender of a 1979 Ford Pinto), or built with very deliberate PCB traces (as with a Raspberry Pi), or incidental (some component of the device behaves as an antenna, even if unintentionally), or a combination of these things, or something else entirely. But whatever its form: An antenna must be present or wireless RF communication simply can't occur. |
