Ultra Wideband Antenna for Future 5G

Abstract

An ultra-wideband miniature antenna based on circular patch with circular slots has been presented for future generation mm-wave indoor wireless applications. The proposed miniature antenna is fed by probe feed and, the maximum realized gain and the total efficiency throughout the three bands are 7.7 dBi in an upper higher band and 97% in the lower band, respectively. This proposed antenna covers the seven bands (five bands are in the existing allocation to mobile, and the other two bands are to be considered for allocation) for 5G higher bands and lower band covers uplink Ku-band (14GHz -14.5GHz) for satellite communication. The proposed antenna in ultra-wideband has the impedance bandwidth of 31.8 GHz and the fractional bandwidth of 60.61%.

“…Various diversity techniques such as spatial diversity, pattern diversity, time diversity, and frequency diversity can be used to solve the issues of multipath fading. [37][38][39][40][41][42][43][44] In this article, spatial diversity and pattern diversity MIMO techniques are used.…”

“…Various MIMO antennas 38,[40][41][42][43][44][45][46][47][48][49] have been published in the literature for 5G communication to solve atmospheric attenuation issues at mm-wave and maximize signal quality at receiver. A 2 × 2 MIMO arrangement of three linked circular rings shaped patches encircled by infinite shaped metallic elements is shown in Reference 38.…”

“…Performance of proposed MIMO configurations is compared with reported antennas 37,38,[40][41][42][43] in Table 9. Proposed antennas have all the MIMO parameters in the acceptable range.…”

“…Wide range of applications has made manufacturers admired by Ultra Wide Band Antennas. However, with the ubiquitous spread of Fifth generation (5G) of mobile communication expected to emerge in 2020 [1], an UWB antenna has become of necessity as a hot topic in industry and research. A narrow wave with a short time (in nanoseconds) covering short distance on a wide bandwidth of frequency domain, with low power emission is very attractive for antenna designers, and defiantly it is what we are presenting in this paper.…”

“…Қазiргi таңдағы мобильдi девайстардың және аппараттардың миниатюрлену үрдiсi антенналардың да өлшемi және сипаттамалары бойынша талаптарға сай болуын қажет етедi. Сонымен қатар, қазiргi таңда ақпаратты қабылдап-жiберу жылдамдағын арттыру мәселелерi сымсыз байланыс технологиясының өткiзу жолақтарын кеңейту арқылы шешiлуде [1][2][3][4][5]. Бұл өз кезегiнде байланыс жүйесiнде көп диапазонды, кең жолақты немесе аса кең жолақты антенналардың болуын қажет етедi.…”
