“…Figure 4 shows the side view of the proposed antenna including the coaxial cable for feeding purposes. In this figure, it can be seen that the total antenna height is 3.604 cm (H + 2SubH) and that although it is large compared to the length of one side of the CubeSat (10 cm) or with other antenna designs such as those reported in [3][4][5][6][7][8][9] in Table 1, the proposed antenna can be part of a Cubesat of more than 1 U, for example, 2 U, 3 U, and so on.…”

As in any satellite, onboard antennas for CubeSats are crucial to establish communication with ground stations or other satellites. According to its application, antennas must comply with standardized requirements related to size, bandwidth, operating frequency, polarization, and gain. This paper presents an ultrawideband circularly polarized two-layer crossed-dipole microstrip antenna for S-band CubeSat applications using genetic algorithms optimization tools included in the 3D electromagnetic simulation software Ansys HFSS. The antenna is constructed on a 10 × 10 cm Cuclad-250 substrate with a back copper flat plane, located at λ/4 at 2.25 GHz operating frequency. The backplane with the exact substrate dimensions improves gain and reduces inside satellite radiation. Measured bandwidth defined by S11 at a −10 dB was higher than 1835 MHz with S11 = −24.68 dB at the central frequency of 2.25 GHz, while measured VSWR at the same frequency was 1.124. At 2.25 GHz, the maximum measured gain and the minimum measured axial ratio in the broadside direction were found to be 6 dBi and 0.22 dB, respectively. There are antenna simulations and measurements, as long as its fabrication guarantees application requirements that make it ready for prespace testing.

“…These antennas operate in S, C, and X bands and provide a total gain ranging from 4.8 to 30.5 dBi. Amongst all patch antenna designs listed in Table 3, i.e., those in [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28], the one in [15] and [16] have the smallest antenna physical size and hence they are suitable for use on 1U, 2U and 3U CubeSats. The design of [15] can also be implemented on the top of the solar cells because of its high transparency and hence allows for surface area reuse due to the integration of the antenna and solar cells.…”

“…They reported simulated and measured reflection coefficients of -25 and -18 dB at 10 GHz with a wide -10 dB bandwidth of 40% (8-12 GHz), respectively and a high measured gain 15 dB at 10 GHz with solar cell. The authors of [24], presented a circular polarized microstrip antenna for both ground and intersatellite communications. The proposed antenna operates in the Sband (2.34 -2.62 GHz) and has a total size of 80mm × 180mm; see Fig.…”

“…Their main limitation, however, is that the inductor equivalent models of the meander-line do not offer flexibility for changing the spacing between meander-line sections. In [24,28,72], the authors used the meander-line approach to achieve miniaturization and good antenna performance. They reported bandwidths ranging from 5-28.7%, and antenna sizes ranging from 0.46lλ 0 ×0.20λ 0 to 2.52λ 0 ×1.24λ 0.…”

Antenna Designs for CubeSats: A Review

et al. 2021

Cube Satellites, aka CubeSats, are a class of nano satellites that have gained popularity recently, especially for those that consider CubeSats as an emerging alternative to conventional satellites for space programs. This is because they are cost-effective, and they can be built using commercial off-theshelf components. Moreover, CubeSats can communicate with each other in space and ground stations to carry out many functions such as remote sensing (e.g., land imaging, education), space research, wide area measurements and deep space communications. Consequently, communications between CubeSats and ground stations is critical. Any antenna design for a CubeSat needs to meet size and weight restrictions while yielding good antenna radiation performance. To date, a limited number of works have surveyed, compared and categorised the proposed antenna designs for CubeSats based on their operating frequency bands. To this end, this paper contributes to the literature by focusing on different antenna types with different operating frequency bands that are proposed for CubeSat applications. This paper reviews 48 antenna designs, which include 18 patch antennas, 5 slot antennas, 4 dipole and monopole antennas, 3 reflector antennas, 3 reflectarray antennas, 5 helical antennas, 2 metasurface antennas and 3 millimeter and sub-millimeter wave antennas. The current CubeSat antenna design challenges and design techniques to address these challenges are discussed. In addition, we classify these antennas according to their operating frequency bands, e.g., VHF, UHF, L, S, C, X, Ku, K/Ka, W and mm/sub-mm wave bands and provide an extensive qualitative comparison in terms of their size, -10 dB bandwidths, gains, reflection coefficients, and deployability. The suitability of different antenna types for different applications as well as the future trends for CubeSat antennas are also presented.
