Abstract:
PROBLEM TO BE SOLVED: To provide an antenna device adaptable to a plurality of frequencies with a simple configuration change.SOLUTION: An antenna device 1 includes: a radiation conductor 2; a first ground conductor 3 on which the radiation conductor 2 is disposed; and a second ground conductor 4, disposed perpendicular to the first ground conductor 3, formed in a tabular shape surrounding the radiation conductor 2. The second ground conductor 4 is detachably fixed to the first ground conductor 3. By installing the second ground conductor 4, the antenna device 1 is capable of receiving an electromagnetic wave of a frequency higher than a frequency in a state where the second ground conductor 4 is not installed.
