MEASUREMENT METHOD OF ELECTROMAGNETIC WAVE ABSORPTION IN THE QUASI MICROWAVE BAND BY THE PRALLEL WIRE LINE

Abstract

The electronic devices using electromagnetic wave increases recently, and the mis-operation of the electronic devices occurs due to the multiple reflection of the electromagnetic wave. The measurement method of electromagnetic wave absorption in the VHP band (80-230MHz) has developed by the parallel wire line method. The method can be applied to the measurement of characteristic on electromagnetic wave absorption, ferrite mortar or carbon mortar, without microwave chamber. In this paper, the measurement method in the quasi microwave band (1700-2600MHz) is developed, the possibility and accuracy of the actual measurement is examined by this research.
