[0002] With the rapid development of satellite navigation technology and its wide application in various fields, higher and higher requirements have been put forward for the antenna characteristics of handheld receiving devices in high-precision satellite navigation and positioning systems. With the development of 4G / 5G mobile communication technology, especially after entering the 5G communication era, the speed of mobile Internet has been greatly improved, which is the choice for more terminals to access the network. Antennas are an important part of terminal products, responsible for transmitting and receiving signals. The antennas used in the existing technology are adjusted to the required frequency band through copper tubes and coils. Since the pitch and length of the coil are not easy to fix, the antenna will be unstable and difficult to debug. Since each coil can only reach one frequency band, there are many types of coils, so the bandwidth, radiation efficiency, gain and directional performance of the antenna directly affect the communication quality of terminal products. In order to meet the requirements of domestic multi-band operators, the bandwidth of 4G / 5G antennas in terminal products needs to cover 820-960MHz, 1710-2690MHz, and 3300-3600MHz.

[0003] In the patent of the Principality with the patent publication number CN117220021A, an omnidirectional rubber stick antenna is proposed. The omnidirectional rubber stick antenna solves the problem of low efficiency gain at low frequency and split petals of the directional pattern at high frequency of the existing antenna, and achieves the technical effect of providing high gain and full coverage in the 4G and 5G frequency bands. After studying the patent and the prior art, it is found that the commonly used full-band omnidirectional communication antenna has the following problems: low efficiency gain at low frequency, which cannot meet customer needs; split petals of the directional pattern occur in the high frequency band, affecting the communication quality. Therefore, an omnidirectional rubber stick antenna is proposed here. Utility Model Content
