Summary: | The invention discloses a large-frequency-ratio single-fed double-frequency common-caliber SIW slot antenna, relates to a new-generation information technology, and provides the scheme for the technical blank of combining single-end feeding with double-frequency multiplexing in the prior art. Energy is respectively input into the high/low frequency radiation cavity in a micro-strip slot coupling mode. During antenna design, the millimeter wave radiation cavity is embedded into the microwave radiation cavity, and the millimeter wave radiation cavity and the microwave radiation cavity are tightly combined to make the design structure compact. In order to reduce signal interference between the high-frequency radiation cavity and the low-frequency radiation cavity and improve isolation, the high-frequency radiation cavity suppresses interference of low-frequency signals by means of self-resonance characteristics and eliminates influence of radiation signals of the low-frequency antenna unit. And the feed microstr |
