Abstract

The invention relates to a double-frequency double-circular polarization common-caliber antenna array for two-dimensional phase control scanning, wherein the antenna array covers a Ka-frequency range and a Ku-frequency range. At the overlapping portion of the two frequency ranges, a basic composition unit of the antenna array is formed by encircling of eight Ka-frequency range metal radiation sheets around one Ku-frequency range metal radiation sheet. At the edge portion, intervals of Ku-frequency range metal radiation sheet need to be adjusted to form an array with a compact layout, thereby effectively reducing a minor lobe and inhibiting a grating lobe. And antennas with different frequency ranges use metal radiation sheets with different polarization modes to form a double-circular polarization state, thereby improving the polarization isolation of the common-caliber antennas. According to the invention, on the basis of the reasonable layout, the antennas with the Ka-frequency range and the Ku-frequency range can be integrated into one caliber; and the mutual influence is minimized by using the means of array optimization and polarization isolation and the like. The antenna array is suitable for various two-dimensional phase control array antenna systems with low-profile requirement and compact structure and two-dimensional phase scanning with the large scanning angle can be realized.

Description

technical field [0001] The invention relates to a dual-frequency dual-circular polarization common-aperture antenna array for two-dimensional phase-controlled scanning, which belongs to the technical field of antennas. Background technique [0002] In order to meet the requirements of low profile, compact structure and large scanning angle in the two-dimensional phased array antenna system, the common-aperture antenna array has become a trend. The common-aperture antennas widely used at home and abroad are not specifically designed for two-dimensional phased array antennas, but most of the common-aperture antennas use waveguide slot antennas or stacked structures to achieve common aperture, and the polarization forms are linear polarization. [0003] The patented dual-band dual-polarization common-aperture antenna (CN201120122507.6), the common-aperture variable-beamwidth waveguide slot array antenna (CN201210011667.2), and the common-aperture antenna involved in a planar wa...
