Abstract
This application provides a transmission absorbing structure and an antenna in-band characteristics test system, relating to design of microwave antennas for radar and communication systems. The transmission absorbing structure includes a coupling feed structure provided with coupling slots for energy coupling with a to-be-tested antenna, two equivalent electric wall structures parallel to each other, and two equivalent magnetic wall structures parallel to each other. The two equivalent electric wall structures and the two equivalent magnetic wall structures together enclose the coupling feed structure, and form a transverse electromagnetic mode (TEM) waveguide. The system includes a vector network analyzer, a to-be-tested antenna electrically connected to the vector network analyzer, and a transmission absorbing structure.
