Abstract: The present invention provides an antenna that enables circular polarization in a plurality of oscillation frequencies. A multi-frequency circular polarization antenna is formed with a substrate and multi-frequency antennas. The multi-frequency antennas are formed with antenna elements, shunt inductor conductors, series capacitor conductors, series inductor conductors, a center point, and input/output terminals. The multi-frequency antenna is arranged to cross the multi-frequency antenna at the center point to make an angle that is less than 90 degrees with respect to the multi-frequency antenna.

Abstract: An antenna device of the present invention includes an antenna element which transmits or receives an electromagnetic wave having a specific frequency by being supplied with electric power, a conductive element which is formed of a conductive material, arranged so as to be spaced apart from and face the antenna element, and serves as a parasitic element, and a housing having a sealed space therein. The antenna element is provided inside the housing, and the conductive element is provided on outer surface of the housing, or in inner part of the housing, or in a mount member by which the housing is worn on a human body, or in a holding member for holding the housing; the conductive element is electromagnetically coupled to the antenna element, resonates with the specific frequency; and transmits or receives the electromagnetic wave.
