“…Higher-order modes are utilized in this design therefore gain as well as the size of the antenna is enhanced. A square slot with two symmetrical notches along with a dumbbell-shaped slot is loaded in the square-shaped SIW cavity [95] for the generation of dual CP resonances. Another substrate layer comprising of SIW cavity loaded with four square patches is stacked over the original substrate for bandwidth enhancement; however, it is difficult to achieve wide axial ratio bandwidth.…”

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.

“…3 Various types of CP antennas have been reported, such as slot-coupled rotated dipole, [4][5][6][7][8] magnetoelectric dipole, [9][10][11][12][13] stacked curl antenna, 14 spiral antenna, 15,16 complementary antenna, [17][18][19] and cavity-backed patch antenna. [20][21][22][23] By placing a dipole above a slot at a certain height, two equal-amplitude, orthogonal linearly polarized components can be generated by appropriately adjusting the height and the rotation angle of the dipole with respect to the slot, thus CP radiation is achieved. 24 This type of antenna features a simple structure and is easily implemented on a planar substrate, making it highly suitable as an mmW CP antenna element.…”

This paper presents a novel wideband circularly polarized antenna that is fed by substrate‐integrated waveguide. Based on the design of placing a pair of chamfered semicircular patches above a slot, a ‐shaped radiator is introduced between the semicircular patches. Multiple resonance points are generated by the combination of the entire radiating structure and a dumbbell‐shaped slot, resulting in improved impedance bandwidth and axial ratio (AR) bandwidth. The proposed element exhibits a wide impedance bandwidth of 50.5% (24.5–41.1 GHz) and an AR bandwidth of 44.2% (25.1–39.3 GHz) with a 44.2% overlapped bandwidth. Then, a 4 × 4 antenna array adopting the sequential rotation technique is constructed. The measured results demonstrate that a 40.6% overlapped bandwidth and a peak gain of 19.1 dBic are achieved. The proposed antenna array shows excellent performance, making it a good candidate for applications in millimeter‐wave wireless communication systems.

“…To realize the dual-band co-aperture antenna, the L-band dipole is bent, and the S-band dipole is placed in the same layer in the empty part of the Lband dipole, taking advantage of the small physical size occupied by the bending dipole. Furthermore, different frequency antennas can also be placed on different layers [17][18][19][20]. In [20], to realize the dual-band antenna coaperture placement in different layers, the antenna etches the weak electric field area in the middle of the upper Cband patch to make room for the normal radiation of the lower X-band patch antenna.…”

This paper proposes a low-profile high-isolation dual-polarization array antenna operating in the L/S band. The radiating unit of the array antenna adopts U-shaped bending dipoles to realize the staggered arrangement of high- and low-band units, and is connected to the feeding network by a coaxial cable. To achieve the non-influence of high-band and low-band feed networks, multi-layer printing technology is used and grooves are etched on the metal plate. In order to reduce the coupling of the high- and low-band dipoles at low frequency, a bandpass filter is added to the high-band feed network, which greatly improves the isolation at low-frequency. The measured results show that the impedance bandwidth of the array is 4.5% (0.971-1.015 GHz) and 7.5% (1.89-2.04 GHz), with gains of 15 and 19 dBi at 1 GHz and 2 GHz, respectively. And the isolation between the dual-polarized ports more than 50 dB and 35 dB was achieved at 1 GHz and 2 GHz, respectively. The proposed array will have practical value in L/S band full-duplex wireless communication systems.
