“…However, only the impedance bandwidth is enhanced while the axial ratio bandwidth remains small. In another design, four chamfered square patches are loaded in four QMSIW cavities in the superstrate layer to achieve wider axial ratio bandwidth [101]. In [58] a cross slot is superstrated by an array of parasitic patches and in [102] four square slots are used as superstrate thereby enhancing the bandwidth and gain both.…”

The increasing demand for efficient data transmission and reception, coupled with high-speed data requirements, is set to drive the extensive global deployment of emerging satellite and terrestrial wireless networks in the next decade. This growth in satellite and terrestrial wireless networks also creates an increased need for reliable and seamless connectivity between ground-based users and satellite communication systems. Substrate integrated waveguide (SIW) antennas offer promising solutions that can serve both terrestrial wireless networks and satellite applications. This review paper presents a comprehensive examination of SIW antennas, exploring their potential applications in both wireless and satellite communication scenarios. An extensive evaluation of various approaches that can be utilized to decrease the size of SIW antennas while also improving their bandwidth and gain are discussed. Also, the design strategies for SIW-based multiband, circularly polarized, dual-polarized, and self-multiplexing antennas designed for satellite communication applications, without relying on rigorous optimization techniques are discussed. Furthermore, the potential future directions and applications of SIW antennas by identifying emerging trends and challenges in the field are also highlighted. Consequently, the review will potentially motivate new research initiatives and directions, while providing valuable guidance for future SIW antenna development and research endeavors.

“…However, the two antennas in [6], [7] have the deficiency of narrow 3 dB axial ratio bandwidth (ARBW) less than 100 MHz and relatively complicated structure, respectively. The sequential rotating feeding network increases the design difficulty in [8], [9], and the separate structure discards the advantages of compact antenna. On the basis of EMSIW, the complementary split-ring resonator (CSRR) technology is employed to design two antennas in [11], [12].…”

A practical method, which based on eighth-mode substrate integrated waveguide (EMSIW), is investigated in this paper to design low-profile antenna with dual-sense circular polarization (CP) and enhanced bandwidth. First, an eighth-mode radiating cavities is presented and excited by single coaxial probe for size reduction and directional radiation. Then, two EMSIW antennas are placed symmetrically and a triangular parasitic patch is introduced between two EMSIW cavities. Attribute to the weakly coupled effect between the radiation aperture and triangular parasitic patch, dual-sense circular polarization characteristic and an additional resonance are acquired. When the triangular patch is transformed into a square parasitic patch, the current path on the parasitic patch is shortened, and a new resonance point is generated at 3.55 GHz. While the resonant mode of the two eighth-mode radiating cavities are almost unaffected and the CP bandwidth varies with the changed current path. Finally, a dual-sense CP EMSIW antenna with extended bandwidth and simple structure is designed and fabricated. The overall size of the fabricated prototype is only 0.57λ 0 × 0.54λ 0 × 0.02λ 0 (λ 0 is the free-space wavelength at 3.4 GHz). Measured impedance bandwidth is 10.5% from 3.24 GHz to 3.60 GHz with an isolation up to 11.6 dB and a maximal gain better than 5.74 dBic in two ports is also achieved. Moreover, the characteristics of dual-sense CP and the cross-polarization suppression capability of up to 20 dB in the main beam are obtained in 3.48-3.60 GHz.INDEX TERMS Eighth-mode substrate integrated waveguide, dual-sense circular polarization, parasitic patch, extended bandwidth.

“…Thus, further improvement in the miniaturization design method is limited. Except for the dual-and triple-mode resonators, QMRs are also investigated to minify circuit scales [18] - [19]. However, no diplexers have been reported based on SIW QMRs, because the modes are difficult to isolate.…”

This paper at first presents the proposal and design of a filtering crossover and diplexer with two second-order filtering channels on substrate integrated waveguide (SIW) quadruple-mode resonators (QMRs) and in a respective single cavity. The proposed method has an interesting application in the overall size miniaturization design. The proposed resonator is yielded with four perturbed modes, TE103, TE104, TE201 and TE202, and featuring distinct electric field distribution, by inserting metal via-holes in the center of a rectangular SIW cavity. Next, a pair of resonances is applied to form a second-order channel filter while TE201 and TE202 modes are implemented to realize the other, thereby integrating the whole circuit in a single cavity. Besides, the transmission responses between the channels are isolated only by the perturbed via-holes. Slots are introduced in the metal surface to further increase each channel design flexibility. In this way, controllable frequencies and compact size have been well achieved. Two examples including a diplexer and crossover with two second-order channels are designed, fabricated, and measured to verify. Good agreement between simulation and measurement can be observed. INDEX TERMS Crossover, diplexer, quadruple-mode resonator (QMR), single cavity, substrate integrated waveguide (SIW).
