“…However, the bandwidth obtained is less than the required minimum of 100 MHz for the 5G band, and the E-plane radiation pattern is tilted at θ = 20º from the broadside direction (θ = 0º). Using fraction-mode structures, one of [39] authors developed various SIW MIMO antennas [40][41][42][43][48][49][50][51][52] from 2019 to 2020. Except [49], which was developed using lossy FR4 substrate, the rest of the works are built on low loss F4B substrate.…”

With the increasing demand for high-speed data, rapid deployments of the 5G terrestrial heterogeneous wireless networks are expected worldwide in the next decade. In such networks, sub-6 GHz macro-cells overlapped by mmWave small-cells are being used to cater to densely populated regions. As a result, several challenges arise with the antenna design technologies used at the mobile terminal, access points, or backhaul/front haul levels. These challenges are being addressed using multiple-input multipleoutput (MIMO), massive-MIMO, and phased array antenna technologies. In order to implement these antenna technologies, considering the expanding 5G scenario, substrate integrated waveguide (SIW) offers a viable solution due to its low-cost, low-profile, high-power handling, low transmission loss, and ease of integration with the radio circuits; therefore, the SIW plays a vital role in developing the modern radio systems. The proposed study aimed to provide a comprehensive overview of SIW MIMO and phased array antennas operating in the 5G sub-6 GHz and mmWave bands. It deliberates the specific issues related to the band of operations and challenges in designing different antenna structures. After careful investigation and detailed analysis, this paper identified existing research gaps and suggested possible antenna design solutions for prospective researchers who intend to explore further the aforementioned promising area and present future research directions.INDEX TERMS 5G New Radio (NR), millimeter-wave (mmWave), multiple-input multiple-output (MIMO), planar antennas, substrate integrated waveguide (SIW), sub-6 GHz. I. INTRODUCTIONThere is rapid growth in the deployments of 5G heterogeneous wireless networks to cater to the increasing demands of high-speed data communication in the modern wireless system [1,2]. In such a scenario, the microwave and mmWave networks overlap (See Fig. 1) to serve the mobile units, access points, backhaul, and fronthaul wireless links, supported by MIMO, massive MIMO, and phased array antennas [1,2]. In order to realize these antennas, substrate integrated waveguide, a well-established planar technology, is a suitable choice [3]. A. MIMO ANTENNAThe multiple-input multiple-output (MIMO) antenna is the key enabling technology for fourth-generation (4G), fifth-generation (5G), and beyond 5G (B5G) wireless communication systems. In 4G communication, MIMO primarily supports average download speeds for mobile users. Whereas, in 5G, the MIMO at the user equipment (UE) side and massive MIMO at the base station (BS) promise to deliver high data speeds for enhanced mobile broadband (eMBB) access and enable a wide range of services, including internet of thing (IoT) and critical machine-to-machine communications [1].As per Shannon's channel capacity theorem, the direct way to enhance the date rate is by increasing the bandwidth and/or signal-to-noise ratio (SNR) [4]; however, these are not under the control of the antenna designer and are fixed by the cellular operator. Therefore, multiple antenna...

This study introduces a new design for an ultra-compact shared-aperture antenna utilizing a quarter-mode substrate integrated waveguide (QMSIW) cavity. The proposed antenna operates as a 4 × 4 multi-input multi-output (MIMO) system in three 5G/6G millimeter-wave (MMw) bands, while functioning as a single element antenna for a 5.5 GHz wireless fidelity Microwave (Mw) band. The antenna comprises four QMSIW cavity resonators; each QMSIW is loaded with dual slots to produce tri-band MMw operation at 28 GHz, 38 GHz, and 0.13 THz. The four cavities are arranged to reuse the entire aperture by creating a conventional open-loop antenna that operates at a frequency of 5.5 GHz. Simulation, measurement, and co-simulation results show that the proposed antenna has a quad-band operation and exhibits favorable characteristics. The measured scattering parameters validate the simulated ones over the four bands under consideration. The lowest values of the measured total radiation efficiencies are 80%, 73%, 62%, and 72% (co-simulation) within the four covered bands, respectively. The antenna peak gains are 1.8 to 1.85 dBi, 4.0 to 4.5 dBi, 4.3 to 4.5 dBi, and 6.5 to 6.6 dBi within the covered bands. Furthermore, the design satisfies MIMO and diversity conditions (envelope correlation coefficient and branch power ratio) over frequency bands of operation. All excellent results are achieved from an ultra-compact size in terms of footprint area (0.018λ02), where λ0 represents the free space wavelength at 5.5 GHz. The antenna boasts an excellent reuse aperture utilization efficiency (RAU) of 92% and a large ratio frequency of 23, making it an ideal candidate for compact devices. With its superior performance, the proposed design is well-suited for a range ofs wireless communication systems, including mobile devices and the Internet of Things.

“…However, it will increase the complexity of the design and the footprints. In order to save space, half-mode, [1][2][3][4][5] cquarter-mode, [6][7][8][9][10] eighth-mode [11][12][13][14] and sixteenth-mode 15 SIW filters are proposed. The size reduction is up to 50%, 75%, 87.5%, and 93.75% separately.…”

This paper proposes novel dual-mode substrate integrated waveguide (SIW) filter and diplexer with circular cavities, in which a pair of symmetrical metallic via perturbations is placed at different positions in a single cavity combining different angle of feeding lines to obtain flexible transmission response. So that multiple transmission zeros can be obtained on one or both sides of the passband. Compared with traditional structure, the proposed dual-mode circular cavity filter and diplexer not only reduce the number of resonators and the volume of filters, but also realize the transmission in higher frequency with the existing machining precision. For verify the structure mentioned above, the dual-mode SIW filter and diplexer are designed, fabricated, and measured in a standard printed circuit board (PCB) process at Q-band. The filter is measured at a central frequency(CF) of 44.86 GHz with a 3 dB fractional bandwidth (FBW) of 10.2%, insertion loss (IL) is 1.9 dB, meanwhile the measured diplexer insertion losses (IL) are 2.1 and 2.4 dB in the lower and upper passbands centered at 38.3 and 44.8 GHz with the fractional bandwidths of 10.7% and 10.1%.The isolation is lower than -40 dB. The measured results show good agreements with the simulated ones.
