“…The SIW has a variety of natural advantages, including high Q value, minimal insertion loss, low profile, and simplicity of integration into planar circuit systems. Therefore, SIW technology has been extensively applied in the design of FSSs to realize high‐frequency selectivity, rapid cut‐off frequency, and so forth 2,15–19 . However, SIW cavities are usually larger than half a wavelength, and the interaction between working modes of the cavity and FSS resonant modes often results in incident angle instability and narrow bandwidth 2,20–24 .…”

This work proposes and investigates a wide‐angle band‐pass frequency selective surface (FSS) with two sharp sidebands. The presented FSS element is made up of three metallic layers and two substrate layers in between, which are surrounded by a substrate‐integrated waveguide (SIW) cavity. The top metallic layer is identical to the bottom layer, composed of a square patch etched with a hexagonal groove, while the middle layer is a similar patch but with rectangular notch edges. This structure achieves a second‐order band‐pass response with highly frequency selectivity on either side of the passband. At the same time, this FSS demonstrates excellent stability for both transverse electric and transverse magnetic polarizations with incident angles between 0° and 60°. The electric current and field distributions are demonstrated for deep analysis. Furthermore, an equivalent circuit model is developed to further understand the operating mechanisms. To verify the validity of the design, we construct a prototype of the SIW‐based FSS (SIW‐FSS) and measured it. There is a fair degree of agreement between the measured and simulated results. Finally, we loaded it onto the horn antenna and tested its application in filtering antennas.

“…It consists of posts with periodic gaps placed along the sidewalls of the structure and hence, provide low leakage loss [5].Cavity backed antennas are evident choices among the designers for low profile antennas as they provide high gain, high power handling capabilities and unidirectional radiation pattern due to suppression of surface waves as compared to the conventional slot antenna [6] - [9].Different SIW structures [10] and single band antennas [11]- [13] are reported in literature. Bandwidth and gain of antenna can be improved using Dielectric resonators [14] or, by using frequency selective surface as superstrate as discussed in [15,16]. Antennas with dual bands of operation are attracting researchers worldwide owing to increase in demand for wireless systems such as global positioning system (GPS), wireless local area network (WLAN) and satellite communication.…”

A low profile circular shaped cavity-backed substrate integrated waveguide (SIW) antenna with two-typical intersecting rectangular slots on the ground plane is designed to operate in the dominant TM010 mode at a frequency of 5.19 GHz in U-NII-1 band for wireless applications. The initially designed antenna produces a gain of 4 dBi with a narrow impedance bandwidth extending from 5.17 – 5.22 GHz. The antenna design is further modified by insertion of another shifted two-typical intersecting rectangular slots to finally resemble that of Hash shape; resulting in dual band antenna operation at 4.9 and 5.93 GHz. The gains obtained are 3.7 dBi and 1.4 dBi for 4.9 and 5.93 GHz respectively with an impedance bandwidth covering 4.88 - 4.92 GHz and 5.92 – 5.94 GHz respectively. The antenna prototype is fabricated using Arlon AD270 substrate material. Parametric studies are performed in terms of return loss and gain of the antenna. All simulations are carried out using HFSS v19.0 and show similar behavior to their experimentally measured counterparts.
