Electromagnetic radiation exposure increases with the rise of the wireless communication devices. Electromagnetic radiation, especially near 2400 MHz band, has gradually increased with the widespread of wireless fidelity adapter in indoor environment. In this study, electromagnetic radiation in dwellings where different Wi-Fi adapters and routers are used was assessed by measuring the electric field and compared with other electromagnetic radiation source and the limits set by the Information and Communication Technologies Authority. Measurements were taken in the range of 760-2690 MHz bands used by GSM, 3G/LTE and Wi-Fi technologies. The detected values for all frequencies are significantly lower than the limits of the Information and Communication Technologies Authority. Among the electromagnetic radiation sources, electromagnetic radiation of Wi-Fi adapter is higher than GSM/3G/LTE sources radiation in dwellings. Electromagnetic radiation values in nearest point of high power adapter Wi-Fi antenna are close to the Information and Communication Technologies Authority limit value. Results show that electromagnetic radiation based on Wi-Fi adapters or routers can be higher than GSM based electromagnetic radiation.

“…Increasing demand on using electronic devices in our daily routine gave a rise on using the particular frequency bands, such as GSM (including 2G, 3G, LTE, and LTE-advanced sub-bands), Bluetooth, and Wi-Fi / Wi-Max in the wireless networks [1][2][3] and EM field emitting devices. Spotlight on these bands caused electromagnetic pollution since the devices have to satisfy the increasing demands of the users regarding high speed, large coverage, mobility, propagation, transmission power, spectrum efficiency, safety, and security [4][5][6][7].…”

This article presents the design, fabrication and analysis of a textile-based band-stop frequency selective surface (FSS), in GSM, WiFi, LTE and WiMAX bands where the electromagnetic (EM) pollution is intense. The unit cell of the proposed FSS has been designed and simulated via a full-wave EM solver; CST Microwave Studio at the frequency of interest. In contrary to traditional FSS designs, which are printed on solid materials such as PCBs, this study presents an FSS considering a woven fabric as a substrate layer having features such as flexibility and compact weight. Two fabrication techniques have been considered one is conducted with a copper tape having a thickness of 35 µm denoted as CT FSS and the second one is conductive yarn embroidering technique denoted as CY FSS for the conducting pattern. Fabricated samples are evaluated in terms of transmission characteristics and a satisfactory agreement is obtained between CT FSS and CY FSS for both simulations and fabricated prototypes.
