Compact 4G MIMO antenna integrated with a 5G array for current and future mobile handsets

Abstract

A novel integrated antenna solution for wireless handheld devices is proposed for the existing 4G standards and upcoming 5G systems for broadband, high data rate communications. The complete antenna system is a unique combination of a multiple-input-multiple-output (MIMO) antenna system at microwave frequencies and a millimeter(mm)-wave antenna array. The MIMO antenna system consists of two reactive loaded monopoles while the mm-wave array consists of a planar 2 by 4 slot antennas. The integrated antenna system covers the frequency bands from 1870 to 2530 MHz for 4G standards along with the upcoming 5G mm-wave band at 28 GHz. In addition, the integrated antenna system is planar and is designed for typical smart phone devices with a standard 60 mm by 100 mm by 0.965 mm back plane. Excellent field correlation values were obtained across the 4G band while realized peak gain values of 4 dBi and 8 dBi were respectively measured for the MIMO and mm-wave antenna arrays. The proposed antenna design may also be useful for other compact implementations that support 4G and 5G communications.

Dual-polarized Dual-band Mobile 5G Antenna Array

“…A Vivaldi phased antenna array performance and it's user effects are investigated in (Ojaroudiparchin et al 2015). In (Hussain et al 2017) a compact 4G MIMO antenna is integrated with the 5G mm-wave mobile array. Two different methods in (Ojaroudiparchin et al 2016) and are introduced in order to create a 3D coverage 5G mm-wave phased antenna array system.…”

“…However, placing multiple antennas in the limited space of a transceiver poses a significant challenge in the incorporation of the MIMO technique. According to the requirement of cellular communications, compact, wideband and high isolation MIMO antenna is an urgent demand in the future mobile terminal and the portable applications [12][13][14][15][16][17]. Recently, several techniques have been introduced to design massive MIMO antennas for 4G and sub-6 GHz 5G mobile terminals [18][19][20][21][22][23][24][25][26][27].…”

“…5 Multiple-input multiple-output (MIMO) antennas are under research and they are having properties like large channel capacity due to multiantennas and can be used to get higher data rates. 6 In literature, several MIMO antennas are available, and some MIMO antennas not only work in the high frequency, but also at lower frequencies for different applications. 7 Designing of a MIMO antenna which works at millimetric wave frequencies have more flexibilities and can achieve high efficiency and lower multipath fading.…”
