TECHNICAL FIELD

[0001] The present application relates to the technical field of scattering antenna, in particular to a portable scattering communication antenna. BACKGROUND

[0002] Compared with satellite communication and other modes, scattering communication has unique transmission characteristics and application fields. Scattering communication has a single-hop span, strong anti-destroying, anti-interference and anti-interception capabilities, and can cross complex terrains such as hills, bays and deserts to perform all-weather reliable communication. Meanwhile, scattering communication is not affected by lightning, sunspots, auroras and other factors. Scattering communication can be used in national defense, rapid reaction force command and emergency communication, and has become an important communication means in strategic, theater and tactical communication networks.

[0003] The deficiency of scattering communication is that, compared with satellite communication, the communication capacity of scattering communication is smaller, and the signal fading and transmission loss are larger, which requires the use of high-power transmitters, high-sensitivity receivers and high-gain antennas.
