NB-IoT and Internet-of-Things satellite fusion antenna

Abstract

The invention relates to an NB-IOT and Internet-of-Things satellite fusion antenna. The fusion antenna comprises an NB-IOT transceiver antenna (3), a row cloud receiving antenna, a row cloud transmitting antenna, a power divider, an A-path SMA-K port (7) and a B-path SMA-K port (8). The NB-IOT transceiver antenna is connected to a NB-IOT transceiver channel, the row cloud receiving antenna is connected to a row cloud receiving channel, and the NB-IOT transceiver channel and the row cloud receiving channel are combined and connected to the A-path SMA-K port (7) through the power divider; and the row cloud transmitting antenna is connected to the row cloud transmitting channel. According to the scheme, the NB-IOT transceiver antenna and the row cloud transmitting and receiving antenna are integrated in one antenna, so that the occupied space is smaller, the antenna adopts an active antenna design, the requirement of integration of a celestial body and a terminal can be met, and the requirement of separation of the antenna and the terminal can also be met.

Description

technical field [0001] The invention relates to the field of satellite antennas, in particular to a fusion antenna of NB-IOT and Internet of Things satellites. Background technique [0002] With the development of science and technology and the improvement of living standards, the Internet of Things communication has begun to enter people's lives. While the Internet of Everything solves the convenience of people's life and work, the problem of signal coverage in areas such as the ground, ocean, and sky is also becoming more and more prominent. The concept of this satellite Internet of Things came into being. Since satellite communication is stable and reliable, and there are almost no coverage blind spots, the communication method using satellite communication can perfectly solve the communication link problem of the ground network under the condition of no signal coverage. [0003] The existing antenna technologies include NB-IoT antenna technology and satellite Internet o...

AI Technical Summary

Problems solved by technology

[0004] Due to the problem of NB-IoT signal coverage and the problem of high power consumption of satellite communication, under most conditions, the two need to be used together, that is, use NB-IoT network communication in places with ground network coverage, and use NB-IoT network communication in places without ground network coverage. Using satellite IoT network communication, in this case, the IoT communication terminal needs to be equipped with two antennas, which brings trouble to the miniaturization of the terminal
