Proposal for a new methodology standard: simple near-field probe measurements of microwave leakage power from gasketed seams

摘要

A simple methodology is described that employs small low-cost probes to measure the total microwave leakage power radiated from practical gasketed seams commonly used in shielding enclosures. This methodology is being proposed for adoption as a standard methodology from very low frequencies (VHF) to perhaps 18 GHz and higher. Experimental results are presented for frequencies between 0.2 and 8.0 GHz. Values of total radiated power measured using the probe methodology agree well with values obtained with the reverberation chamber method. At the present time, a total of only three methodologies are known to have acceptable accuracy /spl plusmn/(3 to 6) dB to qualify as standards, and these are summarized.
