“…By adjusting the parameters of these feed networks, the location of the radiation nulls can be flexibly controlled. In this regard, the foremost consideration pertains to transmission lines endowed with filtering characteristics, such as SIW and rectangular waveguide [212][218], among others. Taking SIW as an illustrative example, owing to its high-pass filtering attributes, antenna designed with SIW as the guiding-wave structure inherently exhibit steep selectivity and higher suppression levels in the lower stopband [224].…”

The fifth generation (5G) mobile communication systems employ technologies such as massive MIMO, millimeter-wave (mmWave), and ultra-dense networks to support higher transmission data rate and lower latency, thereby enabling commercial deployment. Furthermore, the forthcoming sixth generation (6G) networks will integrate terrestrial and non-terrestrial networks, aiming to achieve full spectrum, full applications, and global coverage. Whether in the context of 5G or 6G networks, base transceiver stations (BTS) require a substantial number of radio frequency (RF) transceiver chains and antenna array, particularly in mmWave frequency bands. It is known that bandpass RF filters between antenna elements and transceivers are key components for suppressing out-of-band spurs and interference. The single board seamless integration of transceivers and antennas has become a growing trend. It means there is no extra room for a large number of filters at mmWave bands, leading to the emergence of integrated designs that combine filtering circuitry with antennas, known as filtenna or filtering antenna. With illustrated examples, the design methodologies, operational principles, and implementation strategies of filtennas are reviewed in this paper.

“…Substrate integrated plasmonic waveguides (SIPWs) which have attracted attention in recent years are formed by etching slots on metal layers of the substrate integrated waveguide (SIW) to support the spoof surface plasmon polaritons (SSPP) mode at microwave and terahertz (THz) frequencies [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. The SIPW inherits the characteristics of both SIW and SSPP and exhibits bandpass behavior; its low cut-off frequency depends on the width of the SIW, and its high cut-off frequency can be individually adjusted with the shape and the dimension of the slots.…”

“…The SIPW inherits the characteristics of both SIW and SSPP and exhibits bandpass behavior; its low cut-off frequency depends on the width of the SIW, and its high cut-off frequency can be individually adjusted with the shape and the dimension of the slots. Simple rectangular-shaped and comb-shaped slots have first been proposed in [1][2][3][4][5][6][7][8][9][10][11]. However, to reduce the high cut-off frequency and design more compact microwave and THz devices, the length of slots has to be longer.…”

This paper presents a novel procedure to design a compact and miniaturized unit cell in the substrate integrated plasmonic waveguide (SIPW) structures. The slot of the unit cell is automatically obtained in this method without needing any prior knowledge of its shape. The method is based on topology optimization through pixelization of the slot surface in the unit cell and uses a combination of binary particle swarm optimization (BPSO) and commercial electromagnetic (EM) software. With this method, first, the shapes of the two unit cells are engineered to arbitrarily reduce the high cut-off frequency. Then, two low-pass filters consisting of the proposed unit cells are designed and simulated. To further verify the proposed procedure, one of the filters is fabricated, whose measurement results are in good agreement with the simulation results. This filter provides a pass band of 5.6 to 6.3 GHz and has dimensions of 0.82λg×0.22λg. The proposed method has the potential to minimize microwave and terahertz devices.

Recently, skyrmions are constructed in the system of localized spoof surface plasmons (LSSPs), showing topological robustness and near‐equidistant multi‐resonant response. Guided wave excitation of the LSSP skyrmions plays an elementary role in large‐scale planar integration and construction of complex networks. However, it is not investigated. In this study, the LSSP skyrmions are excited by guided waves supported by two kinds of widely used transmission lines, microstrip line and coplanar waveguide. Space‐coiling meta‐structures with different shapes that support LSSP skyrmions are etched on the ground planes as defected ground structures (DGSs). All structures including resonator, transmission line, input and output ports are in one plane. The structures are fabricated on printed circuit boards (PCBs) and the near‐equidistant multi‐resonant spectra of the LSSP skyrmions are measured. Moreover, to reduce the material loss, the structure is made on MgB2 superconducting film, and the quality factor (Q‐factor) is increased by seven times compared to the corresponding mode on PCB. This study paves the way for the massive planar integration of the LSSP skyrmions and the construction of complex networks with the LSSP skyrmions, and provides an idea for developing metasurfaces with low material loss in the microwave and terahertz bands.
