“…The proposed design can be considered as a compromised solution offering proper performance, and keeping the size parameters of the project. For example, the proposed antenna achieves circularly polarized gain of 5.5 dBic, when it is compared to the published references introduced in Table 4, one can find that this value is smaller than [17], [18], [22], [24], [25]. However, on the other hand the areas of these antennas are much larger than ours.…”

“…The direction of maximum radiation is observed to be in the broadside direction (ϴ = 0 o ). Table 3 illustrates a comparison between the proposed CubeSat antenna and the other antennas in recent literature [16][17][18][19][20][21][22][23][24] related to S-band CubeSat communications. The antenna satisfies the system requirements in Table 1; the size of the antennas and its HPBW lies within the accepted range as listed in Table 1, the F/B approaches 17 dB, more than 5 dBic gain, and LHCP with XPD of 14 dB within the operating band.…”

“…The need for a reflector to minimize the back radiation increases the antenna height. In [22], a steerable Yagi-Uda antenna implemented on a dielectric is proposed. The antenna consists of 3 elements lying on an FR4 substrate that forms an angle with the CubeSat's surface.…”

An Improved S-Band CubeSat Communication Subsystem Design and Implementation

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.

“…A comparison has been included in Table 4, where the advantages of our proposed antenna are highlighted when compared to other state-of-the-art compact designs. Most of these works are based on WLAN and similar applications, however existing Yagi-Uda antennas for CubeSats [26], [27] have also been included in Table 4 to highlight the novelty in our integration approach for small satellites (in that the existing solar cell array of the Unicorn-2 PicoSat spacecraft is exploited) without requiring independent deployable systems for just the antenna. It should also be noted that the proposed three-director design achieves a competitive size when compared with systems of only one or no directors [29]- [32], without sacrificing performance, bandwidth, or involving complex parasitic loading configurations such as parasitic interdigitated strips.…”

“…This antenna design with no miniaturization, needed a substrate of 90 × 150 mm 2 which could be too large for any PicoSat with additional payloads. This led to a modified version in [27] which copper rods embedded in a FR-4 substrate formed a Yagi-Uda array that was mechanically steered to control the beam in the elevation plane. This might increase the complexity and cost, whilst needing the satellite to have the solar panels facing the Earth to achieve full end-fire radiation.…”

A miniaturized planar Yagi-Uda antenna for integration with PicoSats or other SmallSat missions is proposed. Miniaturization techniques, such as meandering and 1-D artificial dielectric concepts to reduce the guided wavelength, are employed to overcome space constraints imposed by the SmallSat footprint while still maintaining good performance for the FR-4 antenna. Simulations and measurements have been carried out on the Unicorn-2 PicoSat chassis from Alba Orbital and are in good agreement. Also, antenna dimensions have been reduced between 15% and 66% when compared to a more conventional planar Yagi-Uda antenna working at the same frequency. This compactness allows for simple integration with the deployable solar panel array of the Unicorn-2 PicoSat spacecraft. Full end-fire radiation is achieved and peak gain values are about 5 dBi for the antenna when fully integrated on the satellite chassis, offering an attractive solution for downlink connectivity. This compact antenna design can also be used within an array for beam steering or integrated within the solar cell modules of other PicoSats, CubeSats and SmallSats. Applications include Earth observation, remote sensing, as well as SmallSat to ground station communications. The planar Yagi-Uda antenna may also be useful wherever end-fire radiation is required from a compact antenna structure.

A novel design of a high‐frequency multiband with a circular polarisation antenna based on a four‐patch antenna system consolidated with an Archimedean spiral antenna for CubeSat applications. The geometry and size are compatible with the CubeSat standard structure dimensions of 10 × 10 cm2. The antenna consists of a spiral antenna in the middle of four patch antennas surrounding it; the first antenna structure consists of two sets of two orthogonal identical patch antennas with a 90° phase shift to cover the band from 1.55 to 1.94 GHz at L‐band, 2, 2.1, and 2.3 GHz at S‐band, the second antenna is an Archimedean spiral antenna to cover all C‐bands, all X‐bands, all Ku‐bands, all K‐bands, and from 26 to 29 GHz at Ka‐band. The measured results show that the reflection coefficients (S11) and (S22) achieve < −10 dB and the axial ratio achieves <3 dB, with a reference impedance of 50 Ω. The simulated and the measured results give a better agreement.
