Ntent-4080da is a double-polarized tightly coupled antenna array covering C-band, which is an ultra-wideband high-power spatial power synthesis antenna solution. It uses a variety of advanced technologies such as metallization technology, tight coupling technology and beamforming technology to realize the radiation of ultra-powerful electromagnetic waves to free space, and can control the spatial synthesis field intensity and focal spot by amplitude and phase. It has been widely used in wireless communication, medical treatment, electromagnetic compatibility and other fields.
