The 8dBi smart cabinet dedicated circular polarization antenna (220) is an antenna designed for unmanned retail and smart container applications. It has the characteristics of small size, thin thickness, high gain, wide wave speed, low VSWR, low axial ratio, etc. . It can be easily applied to UHF frequency band RFID occasions such as warehousing, logistics, assets, unmanned retail, and smart containers.
