“…The reason to etch multiple slots with different lengths and widths is to make the antenna radiate at the desired resonance frequencies and to create a quad‐band radiation characteristic. Thanks to its simplicity, our proposed design has several benefits including more practical fabrication process and better mechanical performance, when compared with presented methods in References 17 and 19. Moreover, the proposed antenna operates at four different 5G communication bands that are 28, 38, 45, and 60 GHz, respectively.…”

“…The proposed antenna is linearly polarized; therefore, positioning the two antenna elements orthogonal to each other to construct the MIMO structure provides polarization diversity. This is a frequently used method for dual polarized MIMO antenna structures 19,20 . The orthogonally placed antenna elements are shown in Figure 11A, where the finalized MIMO antenna width and length are 17.7 and 9.7 mm, respectively.…”

A planar and compact substrate integrated waveguide (SIW) cavity backed antenna and a 2 × 2 multi‐input multi‐output (MIMO) antenna are presented in this study. The proposed antenna is fed by a grounded coplanar waveguide (GCPW) to SIW type transition and planned to be used for millimeter‐wave (mm‐wave) fifth generation (5G) wireless communications that operates at 28, 38, 45, and 60 GHz frequency bands. Moreover, the measured impedance bandwidth (|S11| ≤ − 10 dB) of the antenna covers 27.55 to 29.36, 37.41 to 38.5, 44.14 to 46.19, and 57.57 to 62.32 GHz bands and confirms the quad‐band characteristic. Omni‐directional radiation characteristics are observed in the far‐field radiation pattern measurements of the antenna over the entire operating frequency. The reported antenna is compact in size (9.7 × 13.3 × 0.6 mm3) and the gain values at each resonance frequency are measured as 3.26, 3.28, 3.34, and 4.51 dBi, respectively. Furthermore, the MIMO antenna performance is evaluated in terms of isolation, envelope correlation coefficient and diversity gain.

“…In [18], a cavity mode TE 210 and an additional patch mode are excited to achieve a bandwidth of 15%, which, in fact, is still narrow. Moreover, the published SIW CBSAs are mainly implemented with the ordinary rectangular cavities [4]- [19], circular cavities [20][21][22][23][24][25], triangle cavity [26], and hexagonal cavity [27]. To this end, novel broadband antenna topologies need to be further explored to utilize more cavity modes, aiming to exhibit a wider bandwidth to satisfy the increasing requirement from the modern communication system.…”

Substrate integrated waveguide (SIW) elliptical cavity-backed slot antennas (CBSAs) with either penta-or hepta-resonance are characterized and designed for wideband performance in this paper. First, the resonant behavior of the elliptical cavity is explored. Then the SIW CBSA with penta-resonance is designed by introducing a cross-shaped slot and a pair of unbalanced shorting vias into the cavity to excite two additional odd-and even-half degenerate quasi-TM 110 modes, besides other three modes of half quasi-TM 010 , and odd-and even-quasi-TM 110. Further, by adding another pair of unbalanced shorting vias, two extra higher-order modes, i.e., odd-and even-quasi-TM 210 modes are successfully introduced to design a hepta-resonance antenna. The corresponding mode analysis and design guidelines are discussed in detail. Two prototypes are fabricated and measured at X-band, exhibiting the measured bandwidths of 21.8% and 22.7%, respectively. Measured results agree well with simulations, thus validating the design concept. INDEX TERMS Elliptical cavity-backed slot antenna, mode analysis, wideband applications, substrate integrated waveguide (SIW).

A dipole-type millimeter-wave (mm-wave) antenna with directional radiation characteristics is presented. A radiating patch structure composed of a dipoletype radiation patch and a rectangular-shaped parasitic patch are initially investigated to achieve a wider bandwidth. To further improve the operating bandwidth and to realize a directional radiation characteristic, this radiating patch structure is top-loaded above a conducting cavity-backed ground structure, which has a low profile (thickness of 3 mm). The measured results show that the proposed mm-wave antenna can achieve a wide 10-dB bandwidth of 51.3% (29.6-50.0 GHz) and stable gain across the desired frequency range. Furthermore, good directional characteristics over the entire mm-wave frequency band with a compact antenna size of 0.64λ 40GHz × 0.91 λ40GHz × 0.43 λ40GHz are also realized. Hence, it is suitable for many small size wireless mm-wave systems. K E Y W O R D Sdipole-type, millimeter-wave antenna, cavity-backed, directional radiation | INTRODUCTIONDue to the increasing developments of wireless communication technology, the demand for wider operating bandwidths that provide higher transmission rates are inevitable. 1 Recently, the frequency bands below 6GHz (also known as the sub-6 GHz band) are becoming very crowded because of the significant increase in various wireless applications in these bands. 2 Therefore, the mmwave bands (frequency range of 28-39 GHz) have been selected recently for future applications, such as the fifth generation (5G) application. 3-8 Mm-wave antennas for wireless communication and radar systems were initially developed for military systems, 9,10 and the quality of communication of an mm-wave system is strongly determined by the performances of the transmitting and receiving antennas. Among the various feeding techniques for mm-wave antenna such as the substrate integrated waveguide (SIW) feed and coplanar waveguide (CPW) feed, the CPW feeding is usually the preferred
