“…The antenna geometry and characteristics are optimized to be compatible with any CubeSat standard structure. With the single‐feed and the stacked configuration with no air‐gap, the proposed antenna achieves a simpler configuration and a lower profile in comparison with the previous S‐band CubeSat antennas, for example, see References 7‐12. The antenna features are characterized using the ANSYS electronics desktop and confirmed by experiments.…”

“…It is observed that all antennas yielded comparable performances in terms of footprint size, bandwidth, gain, as well as radiation efficiency. With the stacked structure with no air‐gap, the proposed antenna achieves a lower profile relative to most of the priors 9‐12 . With the single feed, the proposed antenna yields a simpler configuration as compared with the dual/SP feed antennas 7,9,10 …”

“…The sequentially rotated‐phase feed, 7,10 or dual‐feed, 9 however, complicates the antenna design, as well as increases the fabrication cost. In Reference 11, a slot antenna fed by coplanar‐waveguide is presented for CubeSat cross‐links/inter‐satellite communications. The antenna is loaded with a metasurface to improve the gain and reduce the back‐radiation.…”

In this paper, a metasurface‐based antenna with broadband circularly polarized (CP) radiation is presented for S‐band CubeSat applications. It consists of a single‐feed slotted patch and a metasurface composed of 4 × 4 periodic metallic plates. The patch is sandwiched between the finite metasurface and ground plane to excite surface wave resonances for the broadband operation. The antenna is designed to achieve the geometry and characteristics, which are compatible with any CubeSat standard structure. The final prototype with an overall size of 0.64λmin × 0.64λmin × 0.026λmin (λmin is the free space wavelength referring to the lowest operational frequency) has been realized and tested. The experiments result in a |S11| < −10 dB bandwidth of 24.64% (1.85‐2.37 GHz), an axial ratio < 3‐dB bandwidth of 15.23% (1.94‐2.26 GHz), and a broadside realized gain of 5.6 to 6.7 dBic. Moreover, the antenna achieves a good broadside right‐hand CP radiation with symmetric pattern, high front‐to‐back ratio, and high radiation efficiency.

“…The antenna provides a high gain equal to 8 dBic with linear polarization. In [23], a high gain coplanar waveguide (CPW)-fed slot antenna with a metasurface superstrate structure (MSS) is introduced. The use of MSS significantly improves gain, and reduces back-lobe radiation.…”

An Improved S-Band CubeSat Communication Subsystem Design and Implementation

et al. 2021

In the past decade, the majority of the launched satellites have a weight exceeds 1 Ton. Its development takes a long time, high cost, and has a large risk of failure, and does not allow for testing new technologies to avoid the mission's failure. From these points of view, space-tested technologies were preferred to mitigate the risk of failure. Our goal is to build and test our own S-band communication subsystem for CubeSat. The system should be developed with reliable and compact hardware and flexible and efficient software. It consists of passive components such as the antennas and the filters and other active components. The passive components are designed, fabricated and measured while the active components are based on commercial components. In this paper, two antenna boards are designed; one board faces the earth and the other board lies on the opposite side. Each board has two antennas; transmitter and receiver antennas. The transmitter/receiver antennas are operating in the downlink /uplink at frequency bands from 2.2 GHz to 2.29 GHz and from 2.025 GHz to 2.11 GHz, respectively. This configuration keeps the communication between the CubeSat and the ground station to facilitate the de-tumbling process of the CubeSat. The second component is the filters that separate the transmitter from the receiver. The two filters have high roll off and narrow fractional bandwidth within a compact area. The transceiver system is based on the analog devices chip AD9361 controlled by zynq-7000 FPGA. The output RF signal is amplified to approach 33dBm output power to the antenna port via QORVO chip that operates in the range from 700MHz to 2700MHz. The antennas and filters are fabricated and tested where good results are noticed so that they are ready for integrating with the whole CubeSat communication subsystem. INDEX TERMS CubeSat, S-band antenna, hairpin filter, transceiver system, FPGA, and Satellite.

“…Similarly, in Reference [10], the suitability and the challenges of intra-satellite and inter-satellite links in wireless sensor space networks are discussed. Additionally, different types of planer antennas for CubeSats communication applications are studied in [11][12][13]. In Reference [1], the communication capabilities of small satellites over inter-satellite links are presented from the view of the last three lower layers of the OSI.…”

DTN and Non-DTN Routing Protocols for Inter-CubeSat Communications: A comprehensive survey

CubeSats, which are limited by size and mass, have limited functionality. These miniaturised satellites suffer from a low power budget, short radio range, low transmission speeds, and limited data storage capacity. Regardless of these limitations, CubeSats have been deployed to carry out many research missions, such as gravity mapping and the tracking of forest fires. One method of increasing their functionality and reducing their limitations is to form CubeSat networks, or swarms, where many CubeSats work together to carry out a mission. Nevertheless, the network might have intermittent connectivity and, accordingly, data communication becomes challenging in such a disjointed network where there is no contemporaneous path between source and destination due to satellites’ mobility pattern and given the limitations of range. In this survey, various inter-satellite routing protocols that are Delay Tolerant (DTN) and Non Delay Tolerant (Non-DTN) are considered. DTN routing protocols are considered for the scenarios where the network is disjointed with no contemporaneous path between a source and a destination. We qualitatively compare all of the above routing protocols to highlight the positive and negative points under different network constraints. We conclude that the performance of routing protocols used in aerospace communications is highly dependent on the evolving topology of the network over time. Additionally, the Non-DTN routing protocols will work efficiently if the network is dense enough to establish reliable links between CubeSats. Emphasis is also given to network capacity in terms of how buffer, energy, bandwidth, and contact duration influence the performance of DTN routing protocols, where, for example, flooding-based DTN protocols can provide superior performance in terms of maximizing delivery ratio and minimizing a delivery delay. However, such protocols are not suitable for CubeSat networks, as they harvest the limited resources of these tiny satellites and they are contrasted with forwarding-based DTN routing protocols, which are resource-friendly and produce minimum overheads on the cost of degraded delivery probability. From the literature, we found that quota-based DTN routing protocols can provide the necessary balance between delivery delay and overhead costs in many CubeSat missions.
