電体１５０とともに露出させる形態に整える。By adopting the microstrip line type dipole antenna structure obtained above, the conditions for generating microwaves from the surface of the antenna pattern 180 arranged on the antenna substrate 210 are set. Further, since the communication operation can be confirmed between the antenna surface of the RFID tag (FIG. 6) and the antenna pattern surface of the antenna, the tag attached to the antenna has a smaller space and a larger depth than the antenna structures of FIGS. Therefore, the communication can be surely confirmed regardless of the place where it is difficult to confirm the communication.

Microwaves are radiated from any part of the curved line that is bent into a letter, so that the attached tag is narrow and has a large depth, making it easy and quick, regardless of where communication confirmation was difficult. Communication can be confirmed with good reproducibility. (Embodiment 4) FIG. 5 is an overall view (a) of a T-shaped antenna and an enlarged view (b) in which linear conductor portions are connected, showing a fourth embodiment of the present invention. The antenna of this embodiment is of a type in which the length of the coaxial portion is approximately an integral multiple of the wavelength in the tube, and the outer conductor 140 and the inside thereof are made of a resin-based dielectric 1.

The communication check can be performed easily and with good reproducibility in a short time regardless of the place where the communication check is difficult due to its narrowness and depth. Further, in the present embodiment, although the antenna is formed by connecting the linear conductors 241 to each other, the linear conductors 241 may have a spiral shape instead of a straight line.
