Measuring RF Isolation in Shielded Test Enclosures
Review on Measurement of RF Isolation for Small RF Test Boxes
This white paper discusses an isolation measurement method of RF test enclosures with a dimension greater than 2 m and a performance between 300 MHz – 6 GHz. We will also introduce methods for SE measurement in small shielded test enclosures.
What is a shielding enclosure / an RF shielded test enclosure?
It is a structure that prevents any electromagnetic (EM) field from penetrating its interior, and it also prevents environments from the effect of internal EM fields. In general, a shielded enclosure is constructed from metals with a continuous electrical connection in between metallic parts.
What does the term ‘Shielding Effectiveness’ mean when it comes to RF test enclosures?
It is a magnitude ratio of signal received from transmitter antenna without shielding enclosure to the signal received within the RF shield box.
