“…Amid these studies, various antenna design techniques, such as inverted-F, planar inverted-F antenna (PIFA), monopole, and loop, have been proposed. To the above-mentioned structure, slot antennas have also been applied in 5G communication due to their simple structure, wide operation band, and easy integration of active equipment [21][22][23][24][25][26][27]. However, when being used for 5G NR band applications, these slot antennas still have significant margins for improvement in terms of bandwidth utilization and other areas.…”

In this article, a slot-antenna array with wideband and high-isolation for multiple-input multiple-output (MIMO) systems is presented that can be used in fifth-generation new radio (5G NR) communication. The MIMO antenna system is realized by loading six identical antennas (Ant 1-Ant 6) into an FR4 substrate to form a six-port array for a 6 × 6 MIMO system. Each antenna element is a slot antenna type that is composed of a T-shaped open slot and an L-shaped 50 Ω microstrip line. Each T-shaped slot is formed by inserting an I-shaped open branch in the center of the ground plane's U-shaped slot. The L-shaped microstrip line is placed on the upper surface of FR4 to enable coupling feeding in the 3.3 to 5.10 GHz frequency range to cover the 5G NR bands N77/N78/N79. The isolation is increased to more than 18.1 dB by etching the T-shaped slot between the radiation elements on the metal plate. The proposed antenna system was fabricated and tested. The experimental results indicate that the MIMO system can cover the frequency range of 3.20-5.15 GHz with a return loss of 6 dB and provides isolation greater than 16.2 dB. Additionally, a total efficiency greater than 50% and envelope correlation coefficient of less than 0.02 are obtained. The performance under hand-on scenarios is also good. Simulated and measured results indicate that the stated results are consistent. The test results indicate that the antenna satisfies the 5G communication requirements.

This paper presents two new designs of MIMO dual band coplanar waveguide (CPW)-fed-slot antennas operating in the 5G frequency band (28 and 38 GHz). The first antenna is an XX MIMO antenna and the second antenna is an XY MIMO antenna. Simulated results for the S-parameters are presented for the two antennas using HFSS. Measured results are also presented for the return loss and gain with both results showing good agreement. The current distribution, group delay, envelope correlation coefficients (ECC), and diversity gain, are also presented for both antennas. The two antennas are fabricated on a substrate having dielectric constant ε r = 10.7 and substrate thickness 0.635 mm. The size of the antenna is 4.4 mm x 4.1 mm x 0.635 mm.

“…To attain qualified data rates [9] through the 5G non-mm-Wave bands, the massive multiple-input and multiple-output (MIMO) operations are required, which means more 5G non-mm-Wave antennas should be deployed in cellular phones. In addition, to the best knowledge of the authors, based on the literature [4]- [6], [11]- [13] and the commercialized cellular phones [14]- [16], currently, the 5G (or 4G) non-mm-Wave antennas are physically separate from or assembled with the 5G mm-Wave AiP modules, implying additional design efforts and space for the non-mm-Wave antennas are needed. The reported design [17] integrated triband antennas for the wireless local area networks (WLAN) at 2.4 GHz, 5.2 GHz, and 60 GHz on the low-temperature co-fired ceramic (LTCC); however, a considerable clearance area needs to be claimed by the integrated non-mm-Wave antennas.…”

This article presents an inspiring retrospect and prospect on the evolution overview of innovative 5G millimeter-Wave (mm-Wave) antenna designs integrating non-mm-Wave functions based on the antenna-in-package (AiP) solution to cellular phones. The innovative designs include mm-Wave antennas-in-package integrating non-mm-Wave antennas (AiPiA), mm-Wave antennas-in-package as nonmm-Wave antennas (AiPaA), and mm-Wave antennas-in-package integrating and as non-mm-Wave antennas (AiPiaA). In comparison with conventional AiP-based mm-Wave antenna designs, these designs advance to achieve the total solutions for the 5 th generation mobile communications (5G) antennas to cellular phones, which remarkably benefit design efforts of antenna designers for cellular phones, occupied space by antennas in cellular phones, and applications of 5G antennas to cellular phones.
