A compact dual-band antenna with a large frequency ratio and wideband mm-wave capabilities, incorporating multiple input multiple output (MIMO) technology, and designed for high isolation proposed for 5G applications. It contains a substrate-integrated waveguide (SIW) fractal Koch surface (FKS) slot antenna and a patch with L-shaped slots. A wideband performance is achieved by incorporating a novel FKS slot in SIW at Ka-band operation. An L-shaped slot on a coaxial-fed microstrip patch is analysed for achieving circular polarisation in a sub-7 GHz band. The suggested wideband antenna attains improved diversity performance within MIMO systems. A prototype of the proposed antenna is fabricated. Measured results coincide aptly with simulated data. The low-frequency antenna operates at 4.8 and 6.29 GHz with a gain of 4.35 and 3.8 dBi and radiation efficiency of 85 and 88%, respectively. The mm-wave antenna operates from 27.1 to 33.2 GHz, bandwidth of 20.3% with a gain of 8.5 dBi and a peak efficiency of 93%. Isolation of ≥ 50 and ≥ 20 dB is achieved at low and high frequencies, respectively. Envelope correlation coefficient (ECC) value ≤ 0.001 and channel capacity loss (CCL) 0.1 bits/sec/Hz. The proposed MIMO systems exhibit lower Bit Error Rate (BER) performance over the AWGN channel. The design shows significant potential for application in mm-wave massive MIMO base station applications.

“…10 To resolve this BW issue, researchers are utilising two or more resonant modes, higher-order modes, hybrid modes and different slot structures. 11 SIW antenna with two unequal length slots is implemented to improve the BW compared with the standard slot antenna, and the resultant BW is increased by 4% in Mbaye et al 12 Unlike the conventional slot, a long slot and a short slot are paired together to enhance the BW of the SIW slot antenna array. 13 Researchers have also approached enhancing the BW by SIW-fed patches designed in multilayer structures.…”

SummaryThis article analyses a substrate integrated waveguide (SIW) fractal koch surface (FKS) slot antenna performance for Ka‐band applications. This FKS slot shape is obtained by modifying the conventional rectangular slot with the first iteration of the FKS method. The resultant FKS slot behaves as a radiator in the provided space. A single‐ and two‐element FKS slotted SIW antenna characteristics are analysed on a 20 mil thick RT/Duroid 5880 substrate and compared with the conventional rectangular slot. The proposed antenna with dimensions mm3 achieves an impedance bandwidth from 27.4 to 32.1 GHz with a fractional bandwidth of 15.79% and achieves a gain of 8.3 dBi in broadside direction by improving space filling factor in SIW structure. The prototype of the SIW‐fed FKS slotted antenna array measurement results is satisfactory with the simulation results.

With the current advancements in millimeter wave communication, low‐profile structure and power handling capability at high frequencies have become the prime focus for the researchers. substrate integrated waveguide (SIWs), providing better efficiency by exhibiting high‐quality factors and confining EM waves, have become a favorable technology in the antenna regime. Recently, SIWs along with liquid metals have facilitated reconfigurability with extremely thin substrate materials. Antenna on‐chip (AOC) using Complementary Metal Oxide Semiconductor (CMOS) technologies along with Multiple Input and Multiple output (MIMO) applications are showing great potential for researchers in this domain. This review article intends to provide a comprehensive overview of the different types of SIW antennas operating in the 5G band, various SIW topologies, detailed analysis of gain, bandwidth, and isolation. Slotted SIW antennas give exceptional isolation between the bands and low cross‐polarization levels while horn antenna arrays offer wide coverage. Slow wave SIW has achieved an 80% reduction in size with the usage of multi‐antipodal metalized blinds via holes and distributed metal strips. Details on advancement in the artificial intelligence (AI) based SIW antennas are also presented in brief.
