Abstract
A loop antenna providing a reception performance equivalent to a patch antenna receiving a circularly polarized wave, simple in configuration, and kept low in cost, which forms a loop element and a parasitic element provided independently of this loop element on the same dielectric board to form an antenna element and sends or receives a circularly polarized wave by this antenna element, provides a metal plate parallel with or having a slight inclination with respect to the dielectric board, and sets this metal plate separated from the dielectric board by exactly a predetermined distance.
