Abstract

The invention relates to a CTS slot antenna adopting parabolic cylinder coupled feeding. The slot antenna comprises an upper layer radiation layer and a lower layer feed network layer; the radiation layer comprises a parallel-plate waveguide, an upper layer metal parabolic cylinder positioned on the side surface of the parallel-plate waveguide, and a plurality of radiation bodies arranged on the surface of the parallel-plate waveguide; the feed network layer comprise a feed network layer metal plate main body; the feed network layer metal plate main body is provided with feed waveguide; the feed waveguide is connected with a horn antenna; a lower layer metal parabolic cylinder is arranged on the side surface of the feed network layer metal plate main body; and a series of feed coupled slots are formed in the feed network layer metal plate main body. By virtue of the antenna technology, the feed network is simplified, the feed bandwidth is expanded, the outline is relatively low, and the radiation efficiency is relatively high; and the antenna technology has relatively high advantage in the field of millimeter wave, and can be applied to the fields of millimeter wave radar and communication.
