Description
Technical Field
The utility model relates to the technical field of antennas, in particular to an ultra-wideband antenna element.
Background
Compared with WIFI6, the WIFI7 has the advantage that the frequency band of 5.925-7.125GHz (6G for short) is increased on the basis of the original 2.4G and 5G. Due to the requirement of MIMO, the increase of frequency bands can lead to the increase of the number of antennas, the number of antennas is huge, and the integration difficulty is increased. For example, a WIFI7 capping AP, a common antenna combination is 2.4g2+5g4+6g4+ble 1+gps 1, and a total of 12 antennas. If all 12 antennas adopt single-band antennas, the space size of the antennas is larger. If the 5G frequency band and the 6G frequency band can be combined into one antenna (namely 5.15-7.125 GHz), the number of the antennas can be greatly reduced (the number of the antennas is reduced from 12 to 8), thereby achieving the purpose of reducing the size of the antennas. UWB is a popular communication technology for indoor positioning recently, and is favored by the market because of the advantage of high positioning accuracy, however, UWB occupies a very large channel bandwidth, one channel needs to occupy a 500MHz frequency band, and currently, the commonly used frequency bands are 4G (3.7-4.2 GHz), 6.5G (6.25-6.75 GHz) and 8G (7.75-8.25 GHz), and such a large bandwidth brings a great challenge to antenna design.
