“…As shown in Figure 14, the radiation pattern of the proposed Z-shaped MTS-based CP Fabry-Pérot antenna is of RHCP. The AR can be calculated by equation (13) In [11], the CP single-feed hexagonal-shaped patch using superstrate encounters narrow ARBW in spite of wide IBW and high gain. In [13], the Fabry-Pérot antenna with polarization conversion metasurface (PCM) achieves high gain but fails to significantly enhance IBW and ARBW.…”

“…In [10], a single-feed microstrip CP antenna using PRS with 9 × 9 square patch MTS elements as the Fabry-Pérot antenna for C-band spectrum achieves an IBW of 32% (37.4 -52.2 GHz), 3-dB ARBW of 2.58% (5.725 -5.875 GHz), and maximum gain of 17.3 dBic at 5.8 GHz. In [11], a single-feed microstrip patch antenna using the PRS superstrate with 5 × 5 tapered rectangular-shaped MTS elements for X-band spectrum achieves an IBW of 20% (8 -9.8 GHz), 3-dB ARBW of 6.67% (8.35 -8.95 GHz), and maximum gain of 14.6 dBic at 8.3 GHz. In [12], a CP Fabry-Pérot antenna consisting of a rectangle patch antenna surrounded by thin-rectangular-shaped MTS elements as high impedance surface (on the middle substrate) and of 6 × 6 square-split-ring MTS elements (on the upper substrate) functioning as PRS and CP conversion for X-band spectrum achieves an IBW of 2.61% (10.5 -10.78 GHz), 3-dB ARBW of 0.84% (10.65 -10.74 GHz), and maximum gain of 9.8 dBic at 10.7 GHz.…”

This research proposes a low-profile Z-shaped metasurface (MTS)-based wideband circularly polarized (CP) Fabry-Pérot antenna for C-band satellite communication. The proposed low-cost and lowcomplexity CP Fabry-Pérot antenna is realized by using three substrate layers: upper, middle, and lower. The substrates are of FR-4 type with a dielectric constant of 4.3 and loss tangent of 0.025. The upper substrate contains 9 × 9 periodically-arranged Z-shaped MTS unit cells functioning as the partially reflecting surface and circular polarization conversion, and at the center of the middle substrate sits a corners-truncated square patch. The lower substrate consists of a copper plate with an H-shaped slot at the center of the ground plane and a microstrip feed line. The lower and middle substrates function as the source antenna. The periodic Z-shaped MTS unit cells are utilized to enhance the impedance bandwidth (IBW) and gain of the source antenna and also to convert linearly polarized into CP wave. The antenna dimension is 1.5λ0 × 1.5λ0 × 0.51λ0. Simulations are performed and experiments carried out. The measured IBW and axial ratio bandwidth are 64% (4.4 -7.6 GHz) and 18% (4.4 -5.3 GHz) at the center frequency of 5 GHz. In addition, the proposed antenna scheme achieves a measured 3-dB boresight gain bandwidth of 30% (4.3 -5.8 GHz) with the maximum gain of 12.88 dBic at 4.7 GHz, rendering the proposed Z-shaped MTS-based CP Fabry-Pérot antenna operationally suitable for satellite communication. In essence, the novelty of this research lies in the use of the low-cost and low-complexity Z-shaped MTS unit cell to effectively enhance the antenna gain and convert LP into CP wave.INDEX TERMS C-band, fabry-perot, metasurfaces, satellite communication, wideband.

“…CMT has also been adopted for the design of CP MTSs as described in [35]- [37]. Most of these designs operates in the S and C bands but satellite applications are also very active in the X-band where adopted solutions often rely on structures such as horns or reflectarray [38]- [40].…”

A metasurface (MS) based on loop elements operating in the near field of a linearly-polarized microstrip antenna is employed to realize a circularly polarized radiated field. The properties of the loop unit cell are highlighted with the help of the Characteristic Mode Analysis that is employed for investigating the achievable linear to circular polarization conversion bandwidth and providing the guidelines for the design of the final antenna. A finite structure comprising 4×4 unit cells is tailored for achieving a circularly polarized far field within the whole X-band adopted for satellite communications (7.25 GHz-7.75 GHz, 7.9 GHz-8.4 GHz). A simple but effective single-port excitation scheme is adopted, and the overall performance are assessed by measurements on the fabricated prototype. The good agreement between simulated and measured results confirms the reliability of the proposed approach as well as the meaningful insight provided by Characteristic Modes Theory.

“…S-band patch antennas for CubeSat applications are very popular among researchers. Pittella and Nascetti propose a layout based on four rectangular patches on the four sides of a square annular ring, in [15] and [16]. These prototypes are reconfigurable thanks to the changeable phase of the feeding lines.…”

The new space economy paradigm demands for cost-effective systems for its development. Plastic CubeSats are appealing candidates. To enable the use of this new generation of space systems, the challenge of designing suitable communication sub-systems must be faced. In this work, a 3D-printed ABS antenna easily embeddable in a plastic CubeSat is proposed. The 3D-printed material has been characterized in terms of dielectric, mechanical and thermal properties, and the compliance with space requirements has been assessed. In particular, thermogravimetric and calorimetric tests have been carried out. Static and dynamic mechanical analysis were performed. To comply with the stringent weight and space requirements, the unique antenna design of a curved stacked patch has been proposed. The patch covers the uplink (2.025-2.11 GHz) and downlink (2.2-2.29 GHz) bands for Telemetry Tracking and Command (TT&C) applications, with an overall bandwidth of about 300 MHz (14%). Additionally, taking advantage of the curved shape, the proposed antenna shows a size reduction of the resonant length of about 34%. The size of the antenna is 71.5 x 71.5 x 13 mm 3 and is characterized by a weight of only 51 g . Also, in silico tests, by relying on the measured physical properties and a non-linear numerical model, have been carried out to assess the performances of the final antenna layout during a typical CubeSat mission. The proposed design strategy could be used to develop plastic CubeSats embedding performing antennas.
