With the 5G cellular base station testing and large-scale deployment of mobile communication operators. The interference of the 5G spectrum with the FSS Ext.C band (3.4-3.7 GHz) or the standard C band (3.7-4.2 GHz) will become more and more serious. To solve the problem of co-channel interference and adjacent-channel interference in the 5G spectrum, Dolph

Low noise down-conversion module (LNB) in satellite receiving systems with limited frequency selection capability, The signals in the range of 3.0-4.5 GHz shown in Fig. 1(a) are subjected to reception, amplification and down-conversion. Radio regulations and licensing conditions, based on standard (NR) 5G carriers are mainly in the 3.4-3.6 GHz band and are still within

The ring- focus antenna is usually called the parabolic focal axis offset axisymmetric dual mirror antenna. Since the focal trajectory of the antenna is a circle, it is called the circular focus antenna. The ring-focus antenna has its unique position in the satellite communication earth station antenna. Especially in the small and medium satellite communication
