| Abstract: | The field distribution which coupled through the rectangle aperture into metal cavity was researched according to the experiment which incident frequency range was 100 to 1000MHz.The relationship between the size of rectangle apertures and field distribution at the time when the resonance phenomenon was happened was analyzed in this paper,all of which provided experimental evidence to quantitative study on coupling field distribution in cavity with aperture in theory.The experimental study aims at giving some guidance for electronic devices with metal cavity to place correctly the PCB or sensitive components. |
