“…The configuration of the proposed two kinds of fullyshielded combined eighth-mode SIW (FSD-CEMSIW) cavities for two polarizations are given in Fig. 2, which are the fusion of two FSD-EMSIW cavities in [16], and the triangle patches are connected to the ground by some vias. Both high Q resonators consist of three copper layers (t = 35 μm), one dielectric layer (ε r1 = 3.55, tanδ = 0.0027, and h = 0.203 mm) and one prepreg layer (ε r2 = 3.52, tanδ = 0.004, and h b = 0.2 mm).…”

“…Fully-shielded eighth-mode SIW (FSD-EMSIW) cavity proposed in [16] can be a good candidate for mmWave filtenna design due to its compact size, high quality factor, and flexibility in controlling the electrical properties. Nevertheless, power dividers need to be added to excite each radiating element in the subarray, which may cause additional loss.…”

In this paper, millimeter wave (mmWave) filtenna arrays for 5G applications are proposed. Two kinds of 2-element subarrays are designed for horizontal and vertical polarizations. Each subarray consists of three substrate integrated waveguide (SIW) cavities and two sets of stacked patches. Fully-shielded combined eighth-mode SIW (FSD-CEMSIW) cavities are used in the filtenna design. This cavity not only works as the first-stage resonator but also as the power divider for the subarray. As a result, a four-order bandpass filtering response is achieved. Filtenna arrays were fabricated and measured for demonstration. The impedance bandwidths of these subarrays cover 24 -30 GHz, including the 5G mmWave bands (n257, n258, and n261) with measured average gains of 8.2 dBi and more than 22 dB out-of-band suppression. The proposed antennas can be good candidates for 5G mmWave communication to reduce the system complexity and potential cost of the mmWave front-ends.

In this paper, an approach to designing filtering rat‐race coupler (FRRC) with hybrid circular substrate integrated waveguide (CSIW) and coplanar waveguide (CPW) resonators is proposed. The FRRC is developed in a single CSIW cavity embedded with four CPW resonators and four feeding ports, featuring miniaturized size. The desired 0° and 180° phase characteristics of the RRC are realized by the inherent in‐phase and out‐of‐phase electromagnetic fields of the dual‐mode CSIW cavity. By properly arranging the sum, difference and other two output ports, the FRRC is exploited to achieve the desired properties of a RRC with bandpass filtering responses. In addition, transmission zeros are generated in the vicinity of the upper stopband. For validation and demonstration, a miniaturized FRRC utilizing hybrid CSIW and CPW resonators is synthesized, fabricated and experimented in a single‐layered process. Comparisons with previously state‐of‐the‐art research, the proposed FRRC prototype indicates the superiorities of miniaturized footprint, high‐quality‐factor, high‐order filtering response and enhanced out‐of‐band rejection.

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.
