Abstract:

Investigations were conducted to develop test techniques and procedures for making radiated measurements in shielded enclosures which can be correlated with open-field measurements. The primary objective of this program is to develop a capability for determining the case radiation and susceptibility characteristics of U. S. Army communication equipments in the controlled environment of a shielded enclosure. A microwave hooded probe antenna was designed, fabricated and evaluated during this period. The evaluation has demonstrated the capability of this probe antenna in performing radiated measurements in a shielded enclosure over the frequency range from 1 to 12 GHz which have very good correlation with measurements made in the open-field. A UHF hooded probe antenna, for use over the frequency range from 200 to 1500 MHz, has been designed and fabricated. This antenna is presently being evaluated. A theoretical and experimental investigation to determine the field distribution within a shielded enclosure at low frequencies is being conducted. The present status of these programs is discussed. A study to develop technically valid procedures and test setups for use in making measurements in shielded enclosures is also being conducted. A description of the study program is presented. Author
