Problems solved by technology

The bandwidth of the antenna has a great impact on the transmission rate and capacity of the communication system, and is also an important factor affecting the antenna design. Most of the existing ultra-wideband antennas have complex structures and large sizes, which are not conducive to integration with NB-IoT terminals and cannot meet the requirements of NB-IoT. Communication Requirements for IoT Systems

Abstract

The present invention claims a UWB NB-IoT antenna consisting of a side feed metal patch, a 50ohm microstrip feed line, an E-shaped feed structure, a FR-4 dielectric substrate, and a grounding metal patch. The 50ohm microstrip feed line and the E-shaped feed structure are disposed on the upper surface of the dielectric substrate. The grounding metal patch is placed on the lower surface of the dielectric substrate. A rectangular slit is disposed on the grounding metal patch, and an H-shaped coupling feed patch is loaded on the grounding metal patch. The novel UWB NB-IoT antenna of the present invention is selected from a micro-bandwidth slot antenna, achieves excellent UWB characteristics, achieves good impedance matching in 2.45 GHz and 5.8 GHz bands, covers a WLAN band and a Bluetooth band, has a -6dB impedance bandwidth of 0.69GHz to 4.66GHz and 5.58GHz to 7.14GHz, realizes UWB coverage, and is simple in structure, easy to process, and capable of maintaining stable performance in complicated environment.

Description

technical field [0001] The invention belongs to the field of narrowband Internet of Things (NB-IoT), in particular to a novel ultra-wideband NB-IoT antenna. Background technique [0002] In recent years, with the rapid development of the Internet of Things, the communication technology of the Internet of Things has also been greatly improved. NB-IoT (Narrow Band Internet of Things, Narrowband Internet of Things) is one of the latest Internet of Things technologies. It is a new narrowband cellular communication LPWAN (Low- Power Wide-Area Network, Low Power Wide Area Network) technology. Compared with traditional 2G / 3G cellular communication technologies such as GSM, CDMA, and WCDMA, NB-IoT can achieve massive access, ultra-low power consumption and cost. At the same time, the NB-IoT system can provide deep coverage. It achieves strong penetration, and can co-site with the existing mobile communication system to reduce the load on the top of the tower. It has obvious advant...
