Problems solved by technology
[0003] At present, the smart meter uses 433MHz and 470MHz wireless signals to communicate with the concentrator wirelessly, and the 433MHz and 470MHz wireless frequency bands are public wireless frequency bands, which are easily interfered and affected by other wireless signals, which will reduce the communication quality between the smart meter and the concentrator, and even cause communication problems. Interruption greatly reduces the monitoring and guarantee capabilities of power grid power supply quality
The 230MHz power wireless frequency band is a wireless communication frequency band specially allocated by the National Radio Commission for the power grid. It is a spectrum resource with relatively little interference. However, there is no in-table antenna specially suitable for the power grid dedicated frequency band.
[0004] In addition, at present, the State Grid has uniformly standardized the appearance and size of smart meters, and the physical size of the micro-power wireless communication module has also been regulated. Considering the volume occupied by the PCB circuit board, in the micro-power wireless communication module, the antenna The installation space is very limited, and the existing antennas in the frequency band around 230MHz on the market cannot meet the installation space requirements

The invention provides an antenna applicable for a micropower wireless communication module of an intelligent electric meter. The working frequency range of the antenna is from 223MHz to 235MHz, the axial length of the antenna is 39 to 41 millimeters, the diameter of radiation units 101 is 5.3 millimeters, and the spiral distance between the adjacent radiation units is 1.05 to 1.15 millimeters. Through the above design, on the premise of the working frequency range containing 223 to 235MHz power special wireless frequency points, the physical size of the antenna simultaneously meets the installation limitation and requirement of an interior space size of the micropower wireless communication module and also meets the installation size requirement of a printed circuit board (PCB).
Description
technical field [0001] The invention relates to the technical field of antennas, in particular to an antenna suitable for a micropower wireless communication module of a smart meter. Background technique [0002] Smart meters are widely used. Compared with ordinary meters, they have the advantages of remote monitoring and control, and have been installed and used in large quantities in some areas. [0003] At present, the smart meter uses 433MHz and 470MHz wireless signals to communicate with the concentrator wirelessly, and the 433MHz and 470MHz wireless frequency bands are public wireless frequency bands, which are easily interfered and affected by other wireless signals, which will reduce the communication quality between the smart meter and the concentrator, and even cause communication problems. Interruption greatly reduces the power grid power supply quality monitoring and guarantee capabilities. The 230MHz power wireless frequency band is a wireless communication fre...
