Abstract

The invention discloses a planar spread spectrum broadband base station antenna comprising a reflection plate and an antenna radiation unit. The antenna radiation unit is fixed above the reflection plate through a support column and comprises four radiation arms, a dielectric substrate and a feeder structure. The two radiation arms form a +45-degreepolarizing oscillator which is fed by a first feeder, and the other two radiation arms form a -45-degree polarizing oscillator which is fed by a second feeder. The four radiation arms are diamond patches printed on a dielectric substrate, and the diamond patches are provided with right-angle gaps. The antenna has the advantages of planar structure, large bandwidth, simple and novel structure and stable radiation pattern.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a planar spread spectrum broadband base station antenna. Background technique [0002] With the rapid development of mobile communication technology, the development and utilization of new frequency bands is particularly important. Japan has used the 1427-1515MHz frequency band for IMT (International Mobile Communication) services. In Europe, 25 EU countries support the use of 1415-1515MHz for IMT. service, Germany and Italy have already auctioned the center frequency band 1452-1442MHz to IMT service. France, Ireland and Slovenia are consulting with the Cyprus regulator to auction 1452-1442MHz to IMT services. At this stage, there are 2G, 3G, LTE (4G), and 5G systems in China. The 2G system uses 1710-1880MHz, the 3G system uses the frequency band 1880-2145MHz, and the LTE (4G) system uses 1755-2655MHz. Covering the 1710-2655MHz frequency band. With the development of mobile...
