Abstract :
In this paper, beam tilting behavior of radiating slots is introduced. When the radiating field intensity is measured in EMI/EMC test, the receiving antenna or probe must be moved along its vertical axis because of its beam tilting behavior. The radiation pattern is measured by near-field measurement system and verified by the finite difference time-domain (FDTD) method. The far-field pattern was obtained from near far field transformation by using near-field data. The beam tilted about 18 /spl deg/ at 10.82 GHz and the FDTD method provides a good result to this measurement.
