An antenna includes a reflector panel having an inner concave surface and an outer convex surface, a circuit board having two antenna members directed toward different directions and having a terminal coupled to a cable device. The circuit board is received in the concave surface of the reflector panel, and the concave surface of the reflector panel may be used to reflect or to concentrate signals to and from the circuit board. It is preferable that the antenna members are disposed on two opposite surfaces of the circuit board, and directed toward opposite directions. A casing may support the circuit board, and has a channel to receive the circuit board.
