“…Significant and noteworthy volumes of studies and researches have been conducted in the past [4][5][6][7][8][9][10][11], for the 1st, 2nd, 3rd, and 4th generations of mobile communications on health effects, for the whole body and localized tissue heating. At higher frequency bands, such as millimeter wave frequency bands, works need to be done, and studies need to be performed on electromagnetic field exposure.…”

Study on the interactions between electromagnetic fields and biological tissue at high frequency band is an important aspect in the area of wireless communications. The use of millimeter wave frequency band for fifth Generation (5G) devises involves new challenges in terms of Radio Frequency Electromagnetic Field Exposure (RF-EMF) limits and compliance assessment since the basic restrictions for limiting human exposure change from the Specific Absorption Rate (SAR) to the power density. The Electromagnetic Field Exposure to the human head has been studied based on power density by means of numerical simulation for the frequency band of 10 GHz. Study on radio frequency energy absorption has been done based on radiation from a printed monopole antenna at frequency of 10 GHz, transmitting directly towards the human head tissue model. Human head model is constructed from magnetic resonance images with frequency dependent tissue electrical properties. It is shown that at millimeter wave frequency, i.e., 10 GHz, with realistic source (20 mW) and head-source separation distance (10 mm), the amount of power density is in the range of regulatory limits and requirements on EMF exposure. The obtained results might provide valuable information for the design of 5G handheld devices and EMF compliance assessment.

“…Some of them are [8][9][10][11][12][13][14][15]; however, at higher frequency bands such as frequency bands for 5G, electromagnetic field exposure is still unknown and worthwhile for further investigation. Therefore, one of the aims of this study is to investigate by numerical simulations that electromagnetic field exposure of 5G system in biological tissues, which is in the range limit provided by the international standardization organizations.…”

Abstract-The fifth generation (5G) wireless communication systems are projected to work at millimeter wave (mm-wave) frequency bands that would bring new challenges with the implementation of antennas and safety level of electromagnetic field exposures. In this paper, a new design of 5G mmwave antenna for multi-frequency bands has been introduced. The antenna is small enough and has a form factor that can be easily fit into the current available mobile handset devices. The proposed antenna covers all the nominated frequency bands by the FCC for 5G communications and has good radiation performances at 28 GHz, 37 GHz, 39 GHz, and 64-71 GHz. The electromagnetic field exposure to the human head model has been studied by means of numerical simulation for all above frequency bands. The feature of our proposed antenna is that all the frequency bands for the 5th generation mobile handset will be available in a single and simple antenna structure; hence, analysis of EMF exposure in a wide range of frequency can be done on a single antenna design.

“…They were used to cover the surface of the phone in contact to the human phantom cheek, in order to shield the radiation coming to the head. The preparation of the human phantom along with settings of the base station simulator and positioning of the mobile phone in cheek position as in standard [15] are described separately, in [16]. SAR determination was made on a phone model Nokia C5 set in 2G (897MHz) and then in 3G (1950MHz) communication standard.…”
