Problems solved by technology

[0004] Although the above design can achieve the purpose of multi-frequency operation, since the radiating arm 150 and the radiating arm 170 are bent in a Z-shaped symmetrical structure to increase the bandwidth, although this method can shorten the length of the antenna, it also leads to an increase in the overall thickness of the antenna, and The ground plane GPN, ground point G, short-circuit component ST and short-circuit regulator REG must also be bent to reduce the overall volume. Do not install the short-circuit regulator REG, the overall structure of the antenna is too complicated, and the operating bandwidth of the antenna has a certain upper limit, which cannot really achieve the effect of broadband
