摘要：
A system includes a support device and an elongated spiral antenna coupled to the support device. The elongated spiral antenna has a contracted portion and an expanded portion. The expanded portion provides beam steering and directivity. The system also includes a feed line coupled to the elongated spiral antenna. A method for forming the elongated spiral antenna uses a predetermined formula to form arms of the elongated spiral antenna. The arms can be formed by printing the arms on a printed circuit board.
