Abstract

The invention relates to a C / X dual-band common-aperture waveguide slot array antenna, which is mainly used in multifunctional and multipurpose composite radars. The antenna includes an X-band waveguide slot antenna, a radiation transition cavity, and a C-band waveguide slot antenna. The X-band waveguide slot antenna adopts the waveguide narrow-side slanted slit radiation unit, and the C-band waveguide slot antenna adopts the waveguide wide-side slit radiation array antenna. Using the operating frequency difference of the two antennas, the C-band waveguide slot antenna is placed on the X-band waveguide slot antenna After that, the impedance matching between the C-band waveguide slot antenna and the X-band antenna line array gap is realized by using the radiation transition cavity, and the electromagnetic wave radiation of the C-band waveguide slot antenna is realized through the line array gap.

Description

technical field [0001] The invention belongs to the field of radar antennas, in particular to a C / X dual-band common-aperture waveguide slot array antenna, which is applied to multifunctional and multipurpose composite radars. Background technique [0002] With the development of multi-purpose moving platform radar system, more and more functions are required for the radar system on the platform, and the requirements for radar system indicators are getting higher and higher. Radars with multiple frequency bands often need to be deployed on the same platform. The conventional practice of ground radar is to use one antenna for each radar, but the space position of the mobile weapon platform is very limited, and it is impossible to install multiple radar antennas. Therefore, the multi-band common-aperture antenna design technology Gaining importance. [0003] The dual-frequency common-aperture antenna is a dual-frequency antenna array composed of antenna units working in two f...
