    摘要： The invention is method and apparatus for in situ mechanical adjustment of electromagnetic power coupled through an aperture or slot. In its preferred form this adjustment of coupling is achieved by electrically connecting two thin, curved conductive leaf springs (20) to ground plane (14) at the ends of the coupling aperture or slot (12). The springs (20) are curved so as to bend away from the center of the aperture or slot opening (12). The aperture or slot is usually enclosed by a metal backing cavity (22) to prevent radiation from the rear of the aperture or slot and to provide a method for mechanically adjusting the position of springs (20) over the aperture or slot (12), e.g., by adjustment of screws (24). By advancing or retracting screws (24), leaf springs (20) are caused to progressively cover or uncover aperture or slot (12), thereby adjusting the electric field across the aperture or slot (12) and the coupled electromagnetic power through the aperture or slot (12). With this method and apparatus, a wide range of impedance matching to the slot feed line (15) can be adjusted as desired.
