Background
With the advancement of society, the development of mobile communication technology is explosive, and particularly in recent years, the fifth generation mobile communication system 5G has become a hotspot in the communication industry and academia. With the development of the mobile internet, more and more devices are accessed into the mobile network, and the capacity of the mobile communication network is expected to increase by 1000 times over the current network capacity in recent two years. The construction speed of three domestic operators on 5G is in the front of the world, and many cities in China cover 5G signals in urban areas and even suburban areas. The 5G network frequency band numbers of the large-scale construction of three operators at present are n41 (2515-2675 MHz) and n78 (3400-3600 MHz), wherein the n41 frequency band belongs to China Mobile, and the n78 frequency band belongs to China Unicom and China telecom. The 5G base station of the n79 (4800-4900 MHz) frequency band moving in China does not start to be built on a large scale, and in terms of the current construction condition, the n79 frequency band is difficult to land in the next years, the coverage area is small, the barrier penetrating capability is weak, so that operators are required to build denser high-frequency base stations, the cost is high, and complete coverage cannot be realized in a short time. The n41 (2515 to 2675 MHz) and n78 (3400 to 3600 MHz) frequency bands are the primary tasks in 5G communication construction now and for a significant period of time in the future.
For most mobile terminals, the antennas of the mobile terminals need to have omnidirectional radiation characteristics, namely, the antennas are uniformly radiated at 360 degrees in the horizontal direction, namely, the antennas are generally non-directional, so that incoming waves in any direction can be effectively received, and the stability of receiving, transmitting and transmitting of the equipment is ensured. In order to meet the increasing demands of the existing mobile terminal devices for the multi-band operation capability of the antennas, the number of antennas needs to be increased, which definitely increases the volume of the antennas, which is contrary to the miniaturization and high integration pursued by the existing mobile terminal devices. Therefore, it has been urgent to reduce the volume of the antenna while pursuing the multiband operation capability of the antenna, and to achieve miniaturization and high integration of the antenna.
