“…To construct a SIW cavity resonator, two conditions, S via ≤ 2 dvia and d via /λ 0 ≤ 0 1, should be maintained where λ 0 is a free space wavelength. In this way, the SIW cavity acts like a metallic cavity shown [32,36,42,43] and is able to prevent radiation leakage.…”

“…This can be done without even increasing the antenna's overall size. An instance of this is an antenna in [42,43], known as a hybrid antenna, where an array of parasitic patches is used in [42] to escalate the BW of the rectangular HMSIW cavity. Note that patches of the array further cause an improvement in gain and other parameters.…”

“…Note that patches of the array further cause an improvement in gain and other parameters. The experimental validation of the patch array is provided in [42]; however, no experimental data is provided for a single patch with HMSIW. This paper is aimed at providing an indepth analysis with proper experimental validation of that hybrid antenna, single patch with HMSIW cavity.…”

“…Such structure [42,43] can provide wide BW behaviour, and depending upon the requirement, careful design, and substrate specification, UWB behaviour can be obtained. A typical wideband antenna utilizes the operating spectrum efficiently in radar systems with a high spatial resolution for defense systems [44], mobile phones, and many handy devices [45,46].…”

This paper proposes a novel scheme for developing a linearly polarized (LP) hybrid antenna using a simple integration of a planner cavity-backed antenna with a conventional rectangular patch antenna. To substantiate, a half-mode rectangular substrate-integrated waveguide technique is divided into halves to reduce the size and later integrated with a patch antenna. The patch antenna is getting excited by the mutual coupling of TE101 mode and resonating in the vicinity of the cavity resonator. These two different combinations of strategy let the antenna obtain superior characteristics such as bandwidth and gain. To make this structure enable to use in the planner circuit, a 50 Ω microstrip line is incorporated. This proposed hybrid antenna is simulated and tested experimentally to justify its worthiness. The simulated and measured data maintained good agreements regarding S11, bandwidth, gain, radiation pattern, and efficiency.

“…First SIW cavity backed slot antenna was studied in [9], where cavity mode TE 120 and a single slot was utilized for radiation. Since then, various similar SIW slot antennas have been studied [10], [11], [12], [13], [14], [15], [16], [17]. Recently people have started using SIW based antennas for CubeSat applications.…”

In this article, a small aperture coupled SIW cavity-backed dual slot antenna is presented. It is demonstrated that, for a rectangular SIW cavity with dual slot, when the feed point is chosen properly, the structure can resonate at much lower frequency than that of the conventional SIW cavity mode frequency. An equivalent cavity model is formed; a formula for the calculating the operating frequency and a general design guideline are provided for this structure. The designed prototype antenna provides a gain of 8.41 dBi at 15 GHz. For high-gain applications, a 2 × 4 array of such element is demonstrated. An experimental validation of the array results in a gain of 16.01 dBi. The structure is compact, offers a broadside radiation pattern, easy to integrate with metallic surface, and has inherent property of reducing mutual coupling. As a result, it can find application in CubeSat/SmallSats where space is among the major constraints and components are very closely packed. It can be used in CubeSat missions for earth and planetary observations, intersatellite communications, and in MIMO systems for SmallSat swarms.INDEX TERMS Compact antennas, CubeSats, high gain, substrate integrated waveguide (SIW), slot antenna.
