ABSTRACT:
A circularly polarized generator for transmitting circularly polarized transmitted electromagnetic waves and a circularly polarized wave reception antenna for receiving the electromagnetic waves is disclosed. A crank-shaped conductor pattern composed of a pair of U-shaped portions connected to each other so that the open sides of the letter U are directed oppositely to each other is affixed on a substrate, and has its one end arranged as a signal transmitting and receiving end for achieving minimum transmission losses and optimum axial ratio or intersecting polarized wave component discriminating factor as well as for reducing the size and weight and assuring ease of manufacture.
