“…Yi and Wong (2019) have reported an open-slot antenna topology to increase the bandwidth of the slot antenna while keeping the structure simple. The same antenna topology has been used for fabricating an antenna array (Yi and Wong, 2020). As shown in Figure 8, the shorter sides of the slot are not touching the metal boundaries and thus it is called an open slot antenna.…”

Purpose Propagation characteristics of millimeter wave (mmW) frequencies that are being explored for implementing 5G network are quite different from sub 3GHz frequencies in which 4G network is operating, and hence antenna design for mmW 5G network is going to be significantly different. The purpose of this paper is to bring forth the unique challenges and opportunities of planar antenna design for mmW 5G network. Design/methodology/approach A lot of notable contemporary work has been investigated for this study and reported in this paper. A comparison of 4G and 5G technologies has been carried out to understand the difference between the air interface of two technologies that governs the antenna design. Important research gaps found after collating the work already done in the field have been bullet pointed for the use by many researchers working in this direction. Findings Several antenna design considerations have been laid out by the authors of this work, and it has been claimed that mmW 5G antenna design must satisfy these design considerations. In addition, prominent research gaps have been identified and thoroughly discussed. Originality/value As research in the field of mmW antenna design for 5G applications is still evolving, a lot of work is currently being done in this area. This study can prove to be important in understanding different challenges, opportunities and current state-of-art in the field of mmW planar antenna design for 5G cellular communication.

“…With the increasing demand of the mass market for electronics and communication applications, millimeter-wave (mmW) technology, as one of the most promising solutions that help provide high-data rate transmission in the fifth generation (5G) and beyond wireless communications, has become a significant research topic. Waveguide slot arrays [1][2][3][4][5][6][7][8][9][10][11][12][13] are strong candidates for the front-end millimeter-wave waveguide systems, such as radar systems, SATCOM, and 5G wireless communications, due to the advantages of low cost, high efficiency, and high performance.…”

A novel structure of slot antenna with high gain and compact size for millimeter-wave (mmW) applications is proposed. This is the first attempt to apply slow-wave substrate integrated waveguide (SW-ESIW) to the field of antennas and their arrays. Two slot antenna arrays were designed, fabricated and measured. The measured results are in agreement with the simulation. The removal of dielectric substrate improves the radiation gain. At the same time, the slow wave effect, by means of physical separation of electric and magnetic fields, decreases both the lateral and longitudinal dimensions of the antenna. The SW-ESIW slot antenna can achieve miniaturization while retaining the advantages of high gain of ESIW. The 1 × 4-slot array shows a measured −10 dB bandwidth of 16% (30.5–35.8 GHz) with a measured maximum gain of 11.69 dB. The 4 × 4-slot array achieves a measured −10 dB bandwidth of 7.6% from 31.6 to 34.1 GHz with a measured peak gain of 18.75 dB. In addition, during the operating band, the radiation pattern is stable. Compared with the previously structures, the proposed SW-ESIW antenna structure has a better trade-off between gain and footprint. It can be flexibly adjusted to adapt to different requirements. These performances ensure that the antenna array based on the proposed structure is a promising candidate for millimeter-wave wireless applications including the fifth-generation mobile communications.

“…How to broaden their bandwidth has become a hot topic. In [1][2][3][4], the bandwidth is broadened by cutting different shape slots based on antennas. After analysis and verification, they have achieved their desired results and have been applied to different communication frequency bands.…”

A broadband high gain antenna based on metasurface is proposed in this paper. The antenna consists of two layers. The lower layer is a 64 mm×64 mm square substrate, which is fed through aperture coupling to bring the resonant frequencies closer to each other to increase the bandwidth. The upper layer is a substrate of the same size, and the substrate is covered with a metasurface composed of 4 × 4 triangular slots. The impedance bandwidth is expanded by introducing the metasurface from 6.7% of the single-feed antenna(without metasurface) to 23.8%, and the overall height of the antenna is 7 mm. The antenna is excited by an aperture-coupled structure consisting of a microstrip line on the back and a narrow slot etched on the ground surface. The impedance bandwidth of the proposed antenna is 23.8%, ranging from 4.8 GHz to 6.1 GHz. The peak gain at 5.6 GHz is about 11.2 dB, which is relatively stable throughout the operating frequency band. An antenna prototype is made, and the measurement results verify the design's correctness.
