“…Table 2 summarizes the performance of this work and compares it with state-of-the-art mm-wave phased-array antennas [ 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ]. The proposed patch shows around an 8.5 dBi antenna gain, which is better than [ 31 , 35 , 37 , 38 ], at a similar frequency. It describes that the air-filled cavity as a patch gap between the ground increased the antenna efficiency effectively instead of a lossy FR4 PCB material.…”

In this paper, a low cost 28 GHz Antenna-in-Package (AIP) for a 5G communication system is designed and investigated. The antenna is implemented on a low-cost FR4 substrate with a phase shift control integrated circuit, AnokiWave phasor integrated circuit (IC). The unit cell where the array antenna and IC are integrated in the same plate constructs a flexible phase array system. Using the AIP unit cell, the desired antenna array can be created, such as 2 × 8, 8 × 8 or 2 × 64 arrays. The study design proposed in this study is a 2 × 2 unit cell structure with dimensions of 18 mm × 14 mm × 0.71 mm. The return loss at a 10 dB bandwidth is 26.5–29.5 GHz while the peak gain of the unit cell achieved 14.4 dBi at 28 GHz.

“…A microstrip circular patch antenna with a modified Lshaped aperture slot that is coupled to a microstrip feedline is proposed [8]. A phased array eight-element 28 GHz antenna with air hole slots for 5G applications with enhanced half power beamwidth (HPBW) is presented, where the inclusion of circuit elements and liquid crystal display (LCD) panel has to be studied on mobile handsets [9]. A switch-based micro-electromechanical switch (MEMS) based antenna which works at 35.4 GHz frequency with a bandwidth of 6.64% is based on the concept of reconfigurability is presented but the fabricated prototype is not mentioned with validation results [10].…”

A wide variety of technologies are included in various networks under the 5G umbrella. The international telecommunication union (ITU) has given the name "fifth-generation mobile communication systems" to recent millimeter-wave communication technology.Millimeter-wave technology, in general terms, encompasses the electromagnetic spectrum between 30 to 300 GHz, which refers to wavelengths ranging from 10 to 1 mm. The growing memory capacity in handheld connectivity is predicted to produce a high data rate of 10 Gbit/s, which relates to the progression of graphics and data-storage technology. Every indoor wireless communication systems have mixers, amplifiers, antennas, and filters which are essential components of an radio frequency (RF) radio frequency front-end circuit. The demand for microstrip antennas in femtocells plays an important role which can work in both unlicensed or licensed spectrums.*Author for correspondence Femtocells are energy efficient, low cost, selfinstallable, and can be easily manufactured with fifth generation (5G)frequency bands [1]. As the size of the antenna required for 5G femtocells is small, lowprofile antennas like millimeter-wave antennas can be easily preferred where it carries low power and provide enormous bandwidth for communication purpose. In 2019, the Telecom Regulatory Authority of India (TRAI) has given 5G service and sufficient spectrums which are made for the auction.

“…I N order to meet the demands for high data rates, millimeter wave (mmWave) radio frequency bands have been considered in the fifth-generation (5G) communication systems [1], [2]. Due to high path loss and atmospheric absorption at mmWave, a single antenna element won't be able to combat the attenuation [3], [4]. The Multiple-Input Multiple-Output (MIMO) technique, in which multiple antenna elements are deployed both at the transmitting and receiving ends of the wireless system will be used [5], [6].…”

Compact SIW Fed Dual-Port Single Element Annular Slot MIMO Antenna for 5G mmWave Applications

et al. 2021

In this article, a compact dual-port single element MIMO antenna is presented for millimeter wave (mmWave) 5G wireless applications. The presented antenna design consists of an annular ring slot that is fed by a Substrate Integrated Waveguide (SIW) at the two opposite sides of the substrate. The antenna resonates at 28 GHz and its 10 dB impedance bandwidth is 400 MHz. The isolation between the ports is reduced by introducing additional annular slot that acts as a cavity which results in an isolation better than 20 dB at 28 GHz. The measured gain of the both ports are 6.9 dBi which is the highest gain per unit element at 28 GHz in the literature. The measured diversity gain and envelope correlation coefficient are 9.98 dB and 0.065, respectively, at the band of interest. The measured and simulated results are in good agreement.INDEX TERMS millimeter wave, MIMO, slot antennas, substrate integrated waveguide (SIW).
