Electromagnetic shielding tester for conductive textile materials

摘要

Electromagnetic shielding tester has been modified to measure the electromagnetic shielding effectiveness (EMSE) of conductive textile materials using the frequency range 500 MHz - 12 GHz. Various conductive copper filler fabrics have been produced and tested for their electromagnetic shielding effectiveness using both newly modified electromagnetic shielding tester and network analyzer tester (MIL-STD 285), and the values obtained by both the testers are compared and correlated. It is observed that the values measured by the newly modified electromagnetic tester show good EMSE than the network analyzer standard values in the high frequency range 8-12 GHz. The modified system can be used to measure the EMSE of conductive textile materials in the high frequency range 500MHz-12 GHz.
