Electromagnetic radiation probe using a detector circuit with a dual-band antenna system

This paper presents a developed electromagnetic radiation detector system for mainly near-field applications. The prototype employs a dual-band antenna system along with a detecting circuitry with a qualitative electromagnetic radiation strength display unit. The probe is implemented on a printed-circuit board, that makes it suitable for detecting high-frequency electromagnetic radiation applications. Both numerical simulations and experimental validations are presented and discussed. The detecting system has been developed to identify potential sources of electromagnetic radiation from mobile units as well as WiFi access points, simultaneously. The electromagnetic radiation probe will find useful applications as a monitoring probe for troubleshooting and sources of electromagnetic radiation interference threats for industrial high-speed electronic devices, in addition to being a useful tool for site test and scanning for telecommunication service providers.
