ABSTRACT:
A plate antenna for use with polarized waves, wherein pairs of slots are formed in a parallel-plate waveguide, feeding waveguides supply mutually orthogonal TEM waves, the pairs of slots are arranged in a V-shaped pattern, adjacent slot pairs are arranged in mutually opposite directions, the antenna beam can be tilted by adjusting the space between the pairs of slots, and the pairs of slots can induce electric fields in the same direction for horizontal and vertical TEM waves. It is then possible to transmit and receive a horizontal polarized wave and a vertical polarized wave even when the antenna beam is tilted.
