Abstract
Disclosed are a signal transmission device and a smart TV including a wireless signal module. The signal transmission device includes: a main antenna having a first signal input port, the first signal input port being connected with the wireless signal module; a transmission antenna adjacent to and spaced from the main antenna, the transmission antenna having a signal output port; and a dead-zone compensating antenna having a second signal input port. The second signal input port is connected with the signal output port through a signal transmission line, and the main antenna receives signals input by the wireless signal module and transmits the signals, the transmission antenna receives a part of the signals and transmits the part of the signals to a dead-zone compensating antenna through the signal transmission line; the dead-zone compensating antenna transmits the received signals and compensates a signal dead zone of the main antenna.
