PROBLEM TO BE SOLVED: To provide a compact and easy-to-handle antenna device having a communication function and a power feeding function.SOLUTION: An antenna device includes: a feeding unit 21; and a communication unit 31. The feeding unit 21 includes: a first active electrode 23; and a first passive electrode 25, between which a high frequency voltage is applied from a high frequency generator 27. The communication unit 31 includes: a line section 33, having one end connected to a feeding point, electromagnetically coupled with an external device; and a terminating resistor 35 connected to another end of the line section 33. A signal end of a communication device 37 is connected to the feeding point, and a grounding end of the communication device 37 is connected to the terminating resistor. The antenna device is formed in a sheet shape as a whole. |
