“…Its most promising feature is the ability to integrate multiple passive and active components, such as couplers, amplifiers, mixers and antennas on the same substrate, thus forming an integrated platform for efficient circuit design. Indeed, in recent literature, numerous applications of the substrate integrated technology have been thoroughly investigated, confirming the aforementioned advantages and emphasising its role as one of the dominant platforms for implementing millimetre-wave applications [5][6][7].…”

The authors propose a new metamaterial‐inspired substrate integrated waveguide (SIW) that utilises broadside‐coupled complementary split ring resonators (BC‐CSRRs) instead of metalised via holes, to confine propagation within the guiding channel. Due to the resonant behaviour of the BC‐CSRRs, blocking of in‐plane propagation is achieved in a straightforward and efficient manner. The final waveguide is synthesised by employing two rows of CSRRs instead of each via row, resulting in a fully‐planar, easy to fabricate, cost‐effective solution. This new waveguide exhibits outstanding propagation characteristics, with losses close to those of the conventional SIW, providing a highly promising platform to implement low‐cost planar components for millimetre‐wave applications. To further confirm the potential of implementing CSRR‐based SIW components, they provide designs of leaky‐wave antennas in the X‐ and Ka‐band, utilising this new concept.

“…Based on the theory of cavity modes as discussed above, when the number of double-ring slots is 18, each slot is required to withstand the power of 0.9 18 GW at least, and the minimum width of slot w s min can be calculated by (6), so the value is 2 mm. To further increase the power capacity, the slot widths of the inner and outer rings are chosen as 5 and 6 mm, which is much more wider than the slots in [15,[21][22][23][32][33][34].…”

“…In recent years, the slotted-cavity antennas [17,[21][22][23][24] have been studied, and we take advantage of power distribution of highorder modes to realise the reduction in size [25,26]. In [24], the authors first systematically classify HPM antennas and propose a compact HPM feed antenna with shaped beam using the asymmetric high-order mode to make huge reduction in volume compared with other common HPM feed antennas, and obtain higher power capacity and better radiation performance.…”

The coaxial slotted‐cavity antenna is an easily‐manufactured, novel high‐power microwave antenna developed specifically for its compact and shaped‐beam characteristics. It can directly cascade with the high‐power microwave source, and radiate linear‐polarisation electromagnetic wave without extra power dividers and mode converters, which obtains a low profile. In this study, a double‐layer coaxial cavity operating in two high‐order modes is introduced to eliminate the high‐order interference modes caused by structural discontinuities, and three shaped beams on the compact aperture can be achieved by the polarisation cancellation technique. Unique proprieties of three shaped beams, namely the peak of gain enhancement beam, the ripple of Gaussian beam and the null depth of conical beam are investigated, all of which can be controlled by the rotation angle of three phase adjusted slot pairs. This study demonstrates the design process of such antenna, and verifies it against simulation and experimental results. The measured return‐loss of all three shaped beams are higher than 13 dB, while the corresponding radiation efficiencies are not lower than 98.9%. Furthermore, the estimated minimum power capacity of such antenna exceeds 1.26 GW at 9.375 GHz, making it a highly potential candidate in application towards high‐power microwave.

“…Conversely, cavity-backed slot antennas [15]- [18] exhibit excellent electromagnetic shielding capabilities, but generally rely on resonant slots, limiting the bandwidth. Dual-band antennas based on higher-order modes [19]- [20] exhibit a pre-determined frequency spacing between the different bands of operation. Very often, the resonance frequencies are not independently tunable, yielding less versatile performance.…”

A novel dual-band substrate integrated waveguide (SIW) antenna array topology is proposed for operation in the 28 GHz and 38 GHz frequency bands. Four miniaturized quartermode SIW (QMSIW) cavities are tightly coupled, causing mode bifurcation and yielding an antenna topology with four distinct resonance frequencies. A pair of resonances is assigned to both the 28 GHz and 38 GHz band, achieving wideband operation in both frequency ranges. Moreover, owing to the exploited miniaturization technique, an extremely compact array topology is obtained, facilitating easy and straightforward integration. The computer-aided design process yields a four-element antenna array that entirely covers the 28 GHz band (27.5-29.5 GHz) and 38 GHz band (37.0-38.6 GHz) with a measured impedance bandwidth of 3.65 GHz and 2.19 GHz, respectively. A measured broadside gain of 10.1 dBi, a radiation efficiency of 75.75 % and a 3 dB beamwidth of 25° are achieved in the 28 GHz band. Moreover, in the 38 GHz band the measured broadside gain amounts to 10.2 dBi, a radiation efficiency of 70.65 % is achieved and the 3 dB beamwidth is 20°.
