Beschreibung
Zusammenfassung:	The invention discloses a broadband feed-source network in the fields of wireless communication and radio astronomy. The broadband feed-source network comprises two impedance-matching printed boards and a circular polarization bridge, wherein the circular polarization bridge is connected with the two impedance-matching printed boards put in an orthogonal manner, so an impedance value of a wide end of a metal micro-strip line of each impedance-matching printed board is 1/4 of an impedance value of a narrow end of the metal micro-strip line and a narrow end of a corresponding micro-strip ground wire, the feed is simplified and the performance is good. The feed network structure is simple, the feed loss is low, the feed efficiency is high, the structure is compact, the processing cost is low, and the feed network is especially suitable for a feed source or an antenna working in a broadband dual line polarization or dual circular polarization situation.
