<P>PROBLEM TO BE SOLVED: To provide a polarization shared antenna, which forms a bidirectional radio transmission lines by polarization sharing of mutually orthogonal linear polarized waves, such that cross polarization discrimination and isolation between transmission and reception ports are improved at low cost without making a configuration greatly complicated. <P>SOLUTION: The polarization shared antenna includes a plurality of first antenna elements which are arranged in a lattice shape or column state on a predetermined plane and have feeder paths formed individually in a common direction, and a plurality of second antenna elements which are formed opposite the plurality of first antenna elements, and have feeder paths individually formed in a specific direction orthogonal to the common direction, the plurality of second antenna elements individually having slits or cuts formed in the specific direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
