Abstract
This paper presents the design and analysis of the compact patch antenna for 5G and future generation millimetre-wave communication system. The proposed design consists of FR4 substrate length, width, and height of 21.37 x 5 x 1.59 mm3 , besides two rectangular slots incorporated with a dimension of 0.2 x 2.6 mm2 within the patch of 4.22 x 3.46 mm2 , to enhance the resonance frequency more accurate and one more square slot incorporated in to feed line with the dimension of 0.2 x 0.5 mm2 . The obtained return losses of the design is-21.25dB with gain and voltage standing wave ratio (VSWR) of 3.90dBi,1.18 by using a lumped port configuration. For the specific absorption rate (SAR) evaluation considered as a human head model in high-frequency structure simulator (HFSS) software, the obtained values are within the standard limit, the design covers the frequency range of 28GHz, this design may capable of 5G and next-generation wireless communication system application.
Highlights
There are tremendous changes has been observed in mobile communication since last few decades, the mobile devices and connections are getting smarter in their computing capabilities and evaluating lower generation network connectivity technologies i.e.1G, 2G to higher generation technology (3G, 3.5G, and 4G or Long Term Evaluation (LTE)) [1,2]
The first generation technology pertained to voice transmission services only were highly incompatible with related services it was introduced in the early 1980s[2], the second-generation wireless cellular mobile technology was planned for voice transmission with digital data transfer and the data transfer rate up to 64 kbps
International Journal of Antennas (JANT) Vol.7, No.1, January 2021 implies packet-switched data capabilities to existing GSM services and it allows to user can send graphical data as packets, the importance of the packet switching increased with rising of internet and internet protocol (IP),3rd generation technology based on wideband wireless evolution intends to mobile telephone customer to use audio, graphics, and video application data transfer rate up to 200 kbps
Summary
There are tremendous changes has been observed in mobile communication since last few decades, the mobile devices and connections are getting smarter in their computing capabilities and evaluating lower generation network connectivity technologies i.e.1G, 2G to higher generation technology (3G, 3.5G, and 4G or LTE) [1,2]. International Journal of Antennas (JANT) Vol., No.1, January 2021 implies packet-switched data capabilities to existing GSM services and it allows to user can send graphical data as packets, the importance of the packet switching increased with rising of internet and internet protocol (IP),3rd generation technology based on wideband wireless evolution intends to mobile telephone customer to use audio, graphics, and video application data transfer rate up to 200 kbps. This technology enhances the clarity and speed of the network up to megabits per second, for the Smartphone and mobile modems in laptop computers. In the existing present wireless communication world antennas are needed to assure some security of the human body from the electromagnetic radiation for that some of the protecting and guiding organization federal communication commission (FCC), European international electro technical commission (IEC) and IEEE 1528 has set the safety limit of 1.6W/kg absorbed by 1gram tissue and 2W/kg for 10-gram of tissue
