“…A bandwidth of 8.5% is achieved by choosing the length of the two slots according to the two resonance modes. Multiple slots are also loaded in [41,42] to achieve a wide bandwidth of 8% and 3.6%, respectively. The use of multiple slots enhances the bandwidth but at the same instance it also enhances the overall size of the antenna, however, the thickness of the antenna does not get enhanced.…”

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.

“…In [13], a method of corner perturbation in the square cavity enhances the bandwidth (1.65%). In [14], the matching slot excites the TE 210 mode to attain the bandwidth up to 8%. In [15], the TM 010 mode of the patch improves the impedance bandwidth.…”

“…In this paper, bandwidth is improved by perturbing a TE 210 mode instead of multiple modes as compared to the methods reported in [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. Due to the strong loading of an I-shaped slot, the TE 210 cavity mode is perturbed.…”

In this paper, a bandwidth improvement technique in substrate integrated waveguide (SIW) slotted antennas is presented. Here, wideband is achieved by using a single cavity mode (TE 210 ) instead of multiple cavity modes, which is the most distinct approach as compared to other SIW based antennas. When the rectangle slot is loaded at bottom surface of the cavity, the TE 210 cavity mode of the antenna is perturbed. As a result, two independent modes namely odd TE 210 and even TE 210 are successfully generated and merged in close proximity. Consequently, an impedance bandwidth of 12.8% is obtained. When a vertical slit is added at each end of the rectangle slot to make as an I-shaped slot, the impedance bandwidth is increased from 12.8% to 13.94%. The fabricated antenna shows the measured impedance bandwidth of 14.4% and exhibits a gain of 5 dBi to 7 dBi throughout the operating band. The proposed design still retains many features such as light weight, easy fabrication, and easy integration.

In this paper, a bandwidth improvement technique in SIW slotted antennas is presented. Distinct from conventional SIW antennas with multiple cavity modes, a single cavity mode (TE 210 ) is utilized to improve the bandwidth. When a rectangle slot is loaded at bottom surface of the cavity, the TE 210 cavity mode is perturbed. As a result, two independent modes (odd TE 210 , even TE 210 ) are introduced and merged in close proximity. Finally, the antenna is fabricated and tested. The measured results render an impedance bandwidth of 12.8% and a maximum gain of 7.1 dBi. The cross-polar level of maximum −29 dB and −34 dB is at 9.73 GHz and 10.63 GHz, respectively. The proposed design holds many features such as easy fabrication and light weight. Besides, the proposed design is single-layered that makes it extremely convenient to integrate with other planar configurations.
