in fast growing world Mobile phone has become part of the human life. Specific Absorption is a measurement for the amount of Electromagnetic energy that has been absorbed by human tissue ,. Electromagnetic Radiation associated with Mobile Phones is always as an issue that has to be addressed for human safety, Particularly for children. More focus has been paid to induced SAR in the human head when exposed to EM Waves emitted from mobile Phone Antenna, but while using mobile phone the user gets exposed to a dangerous electromagnetic Radiations. ICNIRP Prescribed some guidelines for EM Exposure Level for Public. The Present paper is discuss the SAR Values of different Mobile Phones, Measured How much People are Aware of SAR Values are given as a survey. The study is compromised individuals that visited in the survey site .The awareness is assessed using structured questions and it was recorded to measure the awareness.

“…Although the gain achieved by the antenna element is sufficient, the implementations of electromagnetic band-gap structures (EBG) make the coupling issues severe and the fabrication task difficult. Likewise, array antenna operation at two frequency bands-i.e., 28 GHz and 38 GHz-is proposed in [19]. The high gain of the reported antenna makes this option attractive, but it lacks the MIMO property.…”

In this paper, a novel single layer Multiple Input–Multiple Output (MIMO) antenna for Fifth-Generation (5G) 28 GHz frequency band applications is proposed and investigated. The proposed MIMO antenna operates in the Ka-band, which is the most desirable frequency band for 5G mm-wave communication. The dielectric material is a Rogers-5880 with a relative permittivity, thickness and loss tangent of 2.2, 0.787 mm and 0.0009, respectively, in the proposed antenna design. The proposed MIMO configuration antenna element consists of triplet circular shaped rings surrounded by an infinity-shaped shell. The simulated gain achieved by the proposed design is 6.1 dBi, while the measured gain is 5.5 dBi. Furthermore, the measured and simulated antenna efficiency is 90% and 92%, respectively. One of the MIMO performance metrics—i.e., the Envelope Correlation Coefficient (ECC)—is also analyzed and found to be less than 0.16 for the entire operating bandwidth. The proposed MIMO design operates efficiently with a low ECC, better efficiency and a satisfactory gain, showing that the proposed design is a potential candidate for mm-wave communication.

“…To operate efficiently in these frequency bands, the antenna needs to possess high gain and bandwidth or Multiple Input Multiple Output (MIMO) features [14,15]. In the literature [16][17][18][19][20][21][22][23][24][25], several antennas have been reported for mmWave applications. Reference [17] reported a circular polarized MIMO antenna with four ports.…”

“…Although the antenna covers a huge bandwidth and possesses MIMO features, these are at the cost of the large size. Reference [19] presented a dual band antenna with an array configuration, covering the frequency band between 28 and 38 GHz. The reported antenna achieves a high gain, but it does not possess a MIMO feature.…”

In this work, a new Multiple Input Multiple Output (MIMO) antenna system with a novel shape inspired by nature is proposed for Fifth-Generation (5G) communication systems. The antenna is designed on a Rogers 5880. The dielectric constant of the substrate is 2.2, and the loss tangent is assumed to be 0.0009. The gain of the system for the desired bandwidth is nearly 8 dB. The simulated and the measured efficiency of the proposed system is 95% and 80%, respectively. To demonstrate the capability of the system as a potential candidate for future 5G communication devices, MIMO key performance parameters such as the Envelope Correlation Coefficient (ECC) and Diversity Gain (DG) are computed. It is found that the proposed system has low ECC, constant DG, and high efficiency for the desired bandwidth.
