PROBLEM TO BE SOLVED: To provide an antenna which can suppress bulkiness in a longitudinal direction of an element and has advantage in downsizing and weight saving.SOLUTION: An antenna 3 comprises: a substrate 10; an element 20; and a frequency adjustment unit 60. The element 20 comprises: a main body unit 30 which is made from conductive material and extends in a longitudinal shape in a direction orthogonal to front-back directions; a first connection unit 40 for connecting one end side of the longitudinal direction of the main body unit 30 and the substrate 10; and a second connection unit 50 for connecting the other end side of the longitudinal direction of the main body unit 30 and the substrate 10, where the main body unit 30 is supplied with power through the first connection unit 40. The frequency adjustment unit 60 is installed in the substrate 10 as a conduction path electrically connected to the second connection unit 50, and functions so that a resonance frequency is set depending on a shape or size of the frequency adjustment unit 60. |
