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).
