    摘要: Provided is a capacity loaded planar antenna with short stubs that can be brought to a small size and a low profile, achieves wider bandwidth, and can be tuned to multiple frequencies. A capacity loaded planar antenna with short stubs that has a simple structure and can be easily manufactured includes a base plate, an antenna element disposed so as to be parallel to the base plate, a plurality of short stubs that connect the antenna element to the base plate, and a side wall formed on the end of the base plate. The capacity loaded planar antenna achieves wider bandwidth with the small size and low profiled, can be tuned to multiple frequencies by adjusting the length of the short stubs, and uses plate-shaped foldable short stubs that are integrated with the antenna element.

    摘要: Maintenance information is collected by a sensor on an electric power cable installed in a manhole. The information is transmitted to a radio transmitter which is positioned in a vicinity of a bottom plane of an inner lid in an opening of the manhole. The information is transmitted by the radio transmitter, and received by a receiving antenna mounted on a bottom plane of the inner lid. On a top plane of the inner lid, an electrode, a connecting lead or a transmitting antenna is provided to be connected to the receiving antenna by an impedance matching circuit. The information is supplied to an outer lid in the opening of the manhole by the opening of the manhole by the electrode using a spatial coupling capacitance relative to the outer lid, or the connecting lead directly connected to the outer lid. Thus, the information is transmitted as a radio signal by the outer lid functioning as an antenna. Otherwise, the information is radiated below the outer lid by the transmitting antenna. Thus, the radiated information is leaked via the outer lid to the exterior of the manhole.
