Abstract
An ultra-wideband CTS flat-plate array antenna includes a radiating layer, a mode switching layer and a feed network layer sequentially arrayed from top to bottom. The mode switching layer comprises a first metal plate and a mode switching cavity formed in the first metal plate and including two mode switching units which are arranged left and right and each includes eight H-plane Y-type single-ridge waveguide power dividers arrayed in 4 rows and 2 columns. The H-plane Y-type single-ridge waveguide power divider in the mth row and 1st column is bilaterally symmetrical with the H-plane Y-type single-ridge waveguide power divider in the mth row and 2nd column. The two H-plane Y-type single-ridge waveguide power dividers in the each row are connected through an E-plane T-type single-ridge waveguide power divider. A center distance between every two adjacent H-plane Y-type single-ridge waveguide power dividers in each column is not over one wavelength.
