Summary:An antenna structure for monitoring a manhole is provided to miniaturize an antenna buried under the ground for monitoring the manhole by implementing the antenna as a 1/4 wavelength monopole patch antenna of a planer inverting F antenna type. In an antenna(13) for wireless communication between a plurality of collecting terminals(10) and a relay terminal, the plurality of collecting terminals(10) are connected with a sensor installed inside of a manhole to collect the detection information of the manhole from the sensor. The relay terminal collects and arranges the detection information of the manhole received from the collecting terminals(10). The antenna(13) is provided in a housing(100) of the collecting terminal(10). A circuit board(110) having a connector(120) at one surface is integrally formed with the antenna. The connector(120) of the circuit board(110) and the sensor are connected through a cable(130) passing through the housing(100).
