“…Previous studies have shown that the solar cells affect the antenna's performance as a lossy added substrate and reduce the antenna's gain by about 2 dB [19,20]. But such a gain reduction is still acceptable when considering overall satellite payload and link budget, and it can be improved by using thicker cover glass.…”

“…Although meshed patch antennas find applications in many areas [2,11], the main interest of this study is to provide a transparent antenna design to be integrated with the solar panels of Cube Satellites (CubeSats) in order to save very limited surface real estate [12,13]. Typically, the solar panel of a CubeSat has a solid metal backing (i.e., metallic shielding of the satellite), as illustrated in Fig.…”

“…Due to this solar panel application focus, this paper only studies the meshed antenna backed by a solid ground plane. It is noteworthy that Yekan and Baktur have quantified the effects between solar cells and integrated antennas [12,13] by looking at both solid patch and meshed patch. Yet, since the scope of the study was to understand the interaction between the photovoltaic and electromagnetic components, optimized design for the mesh antenna was not performed as focused in their papers.…”

Abstract-This paper analyzes rectangular and circular patch antennas fabricated from meshed conductors and backed with solid ground planes. Because of the meshing, the antennas are rendered optically transparent, where the transparency is determined by the mesh geometry. It is found that although there is a compromise between the antenna's efficiency and the optical transparency of the meshed patch, it is possible to optimize the antenna by refining mesh lines to certain extent. The limiting factors for refining mesh lines include material handling and fabrication process as well as the increased line impedance when being refined, which accordingly causes loss in antenna's efficiency. A refined mesh with thin linewidth increases both antenna performance and transparency. Additionally, it is found that the reduction of certain mesh lines increases the optical transparency with minimal hindrance to the antenna's efficiency, leading to further enhancement to the see-through percentage. Although it is possible to refine mesh lines to improve the antenna's efficiency or gain, it is seen that there is a limit for such an optimization method. This limit is closer to the efficiency of a solid patch for a lower transparency, whereas it is lower for increased transparency. Cross polarization level was also examined, and there was no significant effect on such a parameter due to meshing.

“…It can be also applied to a patch antenna operating at any frequency band. The designed compact antenna configuration can be used in portable communication devices for X-band wireless sensor applications like different security systems, automatic door openers, automatic sensor lights, automated monitoring systems and also in solar panels [19], etc. The modifications made in the ground plane also generates an additional degree of antenna miniaturisation without affecting the phase tuning mechanism of the fixed size patch in a unit-cell configuration of the reflectarray antenna.…”

This article proposes a new class of miniaturised microstrip patch design for wireless communications at 10 GHz. Antenna miniaturisation is achieved here by loading a highly capacitive modified Minkowski fractal (type‐2) defected ground structure (MFDGS‐II) exactly beneath the center of the radiating patch. The proposed methodology involves sensitivity analysis to select best DGS configuration. The resonant frequency corresponding to the patch is reduced from 16.832 GHz to 10 GHz incorporating MFDGS‐II without any change in the physical size of the antenna. This enables a patch size reduction of as high as 68% and an overall volumetric reduction of 84% along with an improvement in bandwidth and efficiency of the antenna. A prototype of the proposed antenna is fabricated, and its performance parameters are measured. An equivalent transmission‐line model is presented to explain the theoretical background behind the shift in the resonant frequency of the antenna. Our antenna prototype with a lower patch size of 0.20λ0 × 0.15λ0, exhibits an impedance bandwidth of 270 MHz, a realised gain of 3.2 dBi with radiation efficiency of 98% centered at 10 GHz. The proposed compact antenna has the potential to meet the practical requirements for portable X‐band wireless sensor applications.

“…The ground plane of the antenna was also made by wires in [20] (to ensure reduced shadowing), but introduced some undesired back radiation. A CP antenna made by a nearly square meshed patch fed with a coplanar Y-shaped feed, but not integrated on a solar panel, has been proposed in [21]; whereas a uniform patch antenna integrated on a cubesat has been described in [22].…”

Solar-Panel Integrated Circularly Polarized Meshed Patch for Cubesats and Other Small Satellites

et al. 2019

This paper presents the design of a circularly polarized (CP) meshed patch antenna fully integrated within a solar panel for operation on CubeSats and other microsatellites. The structure has been designed to ensure optimal antenna performance at S-band as well as to minimize any shadowing effects that can reduce the received power at the solar cells. To generate CP, the antenna is driven by two orthogonal feed points, penetrating through a transparent borosilicate glass layer, as well as a silicon and PCB substrate. Simulated and measured performances, on both a preliminary FR4 design and a fully integrated prototype, demonstrate a good impedance bandwidth, satisfactorily axial ratio, as well as stable radiation patterns and minimum shadowing levels. The proposed antenna can be useful for communications between satellites as well as with the ground station, and since the structure is compact and completely integrated, the design can be an alternative approach to new-phased arrays on solar panels and other beam-steering systems.
