Abstract
The present invention discloses a dual-frequency feed-source module and a dual-frequency microwave antenna, wherein the dual-frequency feed-source module mainly comprises two coaxially arranged waveguides, the two waveguides respectively provide microwave energy of two different frequency bands to radiating portions for feeding, so that the antenna can be operated in different frequency bands at the same time. The combination of the two coaxial waveguides, a reflector and other structures can form different microwave antennas such as a feedforward dual-band microwave antenna and a feedback Cassegrain dual-band microwave antenna. The invention feeds microwave energy through the two waveguides, so that the antenna can be operated in two frequency bands at the same time, thus greatly expanding an application range of the microwave antenna.
