Abstract: An antenna device of the present invention includes, in one aspect: a patch antenna having a resonant frequency at a first frequency; and a loop antenna having a resonant frequency at a second frequency that is different from the first frequency. A loop length of the loop antenna is such that standing waves are generated in the loop antenna when the loop antenna receives radio waves of the first frequency, and the patch antenna is disposed so as to magnetically couple with the loop antenna.

Abstract: An antenna device including 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 a parasitic element; and a square-shaped housing which includes a wall-thickness portion having a predetermined wall thickness. The antenna element is provided inside the square-shaped housing. The conductive element is provided only inside the wall-thickness portion which is included in any one side of the square-shaped housing, is electromagnetically coupled to the antenna element without being galvanically connected with other components, resonates with the specific frequency, and transmits or receives the electromagnetic wave.
