  • Method for determining the RF shielding effectiveness of a shielding structure
    Patent number: 7173434
    Abstract: Determining the RF shielding effectiveness of a shielding structure including measuring RF isolation between a first and a second element of a directional coupler and providing a first measurement result, placing a shielding structure so that a part of the shielding structure is substantially between the first element and the second element of the directional coupler, measuring RF isolation between the first element and the second element of the directional coupler RF and providing a second measurement result, and determining the shielding effectiveness of the shielding structure based at least in part on the first and the second measurement result.
    Type: Grant
