Embodiment Construction
[0028] Such as Figure 1~4 As shown, the high-power microwave densely-covered slot waveguide antenna of the present invention is composed of a variable-section rectangular slot waveguide 1 and a thin absorbing load 5 . A thin absorbing load 5 is placed at the end of the variable cross-section rectangular slot waveguide 1 .
[0029]The cross-section of the inner cavity of the variable-section rectangular slot waveguide 1 is rectangular. One end of the variable-section rectangular slot waveguide 1 is an open input port, and the other end is a closed structure, which is closed by a metal baffle 4 . There are N slots 3 on one wide side of the variable-section rectangular slot waveguide 1, and the wide side with N slots is called the slot array interface 2, and the metal wall thickness of the slot array interface 2 is t a , the length direction of the slot is perpendicular to the axis of the waveguide, the width of the slot is w, and the length of the nth (n=1,2,3,...,N) slot is ...
