Abstract

The invention provides a dual-waveband common-caliber antenna. The dual-waveband common-caliber antenna comprises a C-band horizontally-polarized antenna, a C-band vertically-polarized antenna and an L-band vertically-polarized antenna, wherein the C-band horizontally-polarized antenna and the C-band vertically-polarized antenna are waveguide slot antennas, the L-band vertically-polarized antenna is a long slot antenna, the C-band horizontally-polarized antenna and the C-band vertically-polarized antenna employ waveguide end feed, and the L-band vertically-polarized antenna employs coaxial feed. The dual-waveband common-caliber antenna has advantages of compact structure, flexible feed, high isolation level, high caliber efficiency, light weight, electrical scanning, double bands and multi-polarization property and is convenient for large-scale array plane establishment.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a dual-band common-aperture antenna. Background technique [0002] Synthetic aperture radar has higher and higher requirements on the antenna system. It is often hoped that the antenna has multi-band, multi-polarization, and common aperture performance under the premise of ensuring performance. The combination of the above features can provide the radar with more information about the imaging area, and can greatly reduce the size of the antenna and reduce the weight of the system. [0003] However, the current dual-band common-aperture antennas mostly use microstrip antennas, but the efficiency of microstrip antennas is low, and the environmental adaptability is not as good as that of metal conductors. [0004] Chinese invention patent CN 104795638A discloses a dual-band circularly polarized co-aperture microstrip antenna, and the miniaturization of the antenna can be realized ...
