“…The dual polarization has been achieved in [ 8 ] as CP and in [ 46 ] as LP without pattern diversity and reconfigurability based on slot antenna and shared aperture antenna, respectively. On the other hand, the antennas in [ 3 , 8 , 38 , 40 , 47 , 48 ] achieved CP with a complicated structure. Therefore, the proposed antenna is a good candidate for future CR-IOST applications.…”

Since the CubeSats have become inherently used for the Internet of space things (IoST) applications, the limited spectral band at the ultra-high frequency (UHF) and very high frequency should be efficiently utilized to be sufficient for different applications of CubeSats. Therefore, cognitive radio (CR) has been used as an enabling technology for efficient, dynamic, and flexible spectrum utilization. So, this paper proposes a low-profile antenna for cognitive radio in IoST CubeSat applications at the UHF band. The proposed antenna comprises a circularly polarized wideband (WB) semi-hexagonal slot and two narrowband (NB) frequency reconfigurable loop slots integrated into a single-layer substrate. The semi-hexagonal-shaped slot antenna is excited by two orthogonal +/−45° tapered feed lines and loaded by a capacitor in order to achieve left/right-handed circular polarization in wide bandwidth from 0.57 GHz to 0.95 GHz. In addition, two NB frequency reconfigurable slot loop-based antennas are tuned over a wide frequency band from 0.6 GHz to 1.05 GH. The antenna tuning is achieved based on a varactor diode integrated into the slot loop antenna. The two NB antennas are designed as meander loops to miniaturize the physical length and point in different directions to achieve pattern diversity. The antenna design is fabricated on FR-4 substrate, and measured results have verified the simulated results.

“…In these studies, PD controllers are commonly used as the control law, based on error and rate matching, with various methods of motion specification. Quaternion representations are frequently encountered in these studies [13,24]. In the work [25], several parameterizations of motion relative to the center of mass are presented, along with the corresponding control laws for each parameterization.…”

“…One of the approaches is using integrated antenna systems with solar panels or payloads. By integrating antennas into the surface area of the CubeSat, it becomes possible to simultaneously utilize the limited space for both communication and power generation purposes [10][11][12][13][14]. This integration eliminates the need for separate dedicated antenna structures, saving valuable space and reducing the overall size and weight of the CubeSat.…”

One of the future challenges of increasing the harnessed solar power is efficiency using of CubeSat sides. One of the approaches is using integrated antenna systems with solar panels or payloads. This study proposes a new approach to the use of integrated antenna systems in remote sensing missions. In this approach, due to the integration of antenna system with payload (in our case, with camera), it is possible to achieve a significant increase in the power generation. Calculations are carried out for cases when the antenna system are integrated with the optical system (α = 0°), which implies that they use one plane, in the second case they are spaced at an angle of α = 90° and in the third case when they are directed to opposite sides (α =180°). In the case of α = 0°, where the camera and antenna module are aligned co-axially, there is no energy expenditure for CubeSat orientation. However, in the other two cases, energy is required for rotation and maintenance of the specified orientation throughout the entire duration of the satellite's flight over the ground station, amounting to 111.99 mW when α = 90° and 44.33 mW when α = 180°.

A helix antenna serves as an electromagnetic emitter that transmits signals in the shape of a coiled thread. It possesses two primary operational modes: normal and axial. In the axial mode, radiation peaks along the helix's axis, creating a near-circular concentration of electromagnetic waves. This paper delves into the intricacies of designing a spiral antenna optimized for operation at a 3 GHz reverberative frequency. It exhibits indirect polarization and is ideally suited for wireless communications, facilitating the transmission and reception of VHF waves, especially for ionospheric propagation. The versatility of this antenna extends to various applications, including radio astronomy, space telemetry, satellites, and space-based communication systems. The proposed antenna design showcases a directional radiation pattern with a notable gain of 13.8 dB. Future research will explore its adaptability for deployment in aquatic environments, expanding its utility in scenarios that demand reliable wireless connectivity beneath the surface. This innovation holds great promise for enhancing communication capabilities across a range of fields and environments.
