MONOPOLE ANTENNA WITH CONDUCTIVE REFLECTOR

PROBLEM TO BE SOLVED: To provide a monopole antenna with a conductive reflector which reduces the influence of outdoor interference waves on services of indoor automobile phone, cellular phone and other mobile telephones by increasing a FB ratio and providing quality serves. SOLUTION: The monopole antenna forms a deep direction conductive plate by bending it orthogonal to an upper end portion of the conductive reflector in the monopole antenna with the conductive reflector which fixed-connects a monopole antenna element electromechanically to a ground plate and forms the conductive reflector, in parallel with the monopole antenna element at the deep direction end portion of the ground plate.
