Summary:
This paper shows a development of an E-field probe in a personal exposure measurement meter for occupational exposure. To evaluate an exposed E-field near the human body, the personal exposure measurement meter is used. This device composes of the E-field probe and a readout device. The probe is consist of three orthogonal small dipoles with diode and lossy transmission lines with chip resistors. To improve the probe sensitivity, the use of various chip resistors has been proposed in this paper. The bandwidth of the designed E-field probe is from 800 MHz to 2.5 GHz for mobile communication bands. The fabricated E-field probe with variable resistors and the characteristics of the probe such as linearity and isotropic deviation are presented in this paper.
