Принадлежит:

The invention relates to a double-frequency common-caliber composite antenna, belongs to the technical field of antennas, and solves the problems of low radiation efficiency, narrow bandwidth and large size of a composite antenna in the prior art. The double-frequency common-caliber composite antenna comprises an X-frequency-band metal oscillator antenna and a Ka-frequency-band waveguide slot antenna, the X-frequency-band metal oscillator antenna and the Ka-frequency-band waveguide slot antenna are stacked in sequence from top to bottom, and the wavelength ratio of the X-frequency-band metal oscillator antenna to the Ka-frequency-band waveguide slot antenna is 1: 4. The dual-frequency common-caliber composite antenna adopts a common-caliber composite form, greatly saves the design space, realizes dual-frequency combination, and has the characteristics of wide band, dual frequency and high radiation efficiency.
