This project is about A Multi-Band Integrated Electromagnetic Field Detection System where it can be used, how it can detect and compare the radiation with its safety level of electromagnetic. Electromagnetic radiation has been a common concern in most developed and developing countries in terms of the hazard it poses upon human‟s health and its capabilities of reducing efficiency of electrical and electronic devices in its surrounding. This system is designed to help human in daily life to avoid the exposure to electromagnetic radiation at telecommunication base station, hospitals or any placed exposed to radiation. The system is capable of detecting the level of electromagnetic radiation (in volts/meter) by the antenna at the frequencies of 0.9GHz, 1.8GHz and 2.1GHz and compared with the safety limits set by international standard (ICNIRP). Experimental setup has been carried out using GTEM cell and RF measurement instruments to validate the efficiency and preciseness of the designed electromagnetic radiation detector. The designed unit contains receiver stage which is rectangular microstrip patch antenna, detector and amplifier stage which is used to amplify and produce accurate DC voltage, microcontroller circuit which is used to compare the received value with the safety value of electromagnetic radiation and interfacing the hardware with PC using GUI. The output on the PC is an emitting diodes light coloured which is either green for safety, orange for critical or red danger.
