“…Such an integration can be particularly valuable for a CubeSat (a very small satellite designed with modular components to have a minimum payload) [4] as the antennas, when effectively integrated with the solar cells, do not compete with solar cells for the limited surface real estate. There have been four main types of integrations reported: (1) antennas integrated under solar cells [1,[5][6][7]; (2) antennas integrated on the same plane with or on the side wall perpendicular to solar cells [8][9][10]; (3) antennas integrated on top of solar cells [11][12][13][14][15][16][17][18], and (4) parts of the solar cells function as antenna [19][20][21] (the antenna in [7] also belongs to this category as the solar cell above the antenna acts as a parasitic elements of the antenna). The third type of integration is of particular interest and promise to a CubeSat system as the antenna topology, especially when it is small or optically transparent, facilitates a possible modular design.…”

“…For the effect of the solar cell on the antenna integrated on top, the reported results are limited. The objective of the research in [14,15] was on the transparency or bandwidth of the antenna, and hence, there is no report on the effect of the solar cell. The dielectric resonator antenna in [13] was reported to have little effect on the solar cell, however, there was not sufficient information given on the specific solar cell, and hence the conclusion from [13] may not be applicable to satellite solar cells.…”

Abstract-A patch antenna integrated on the cover glass of a commercial space-certified solar cell is examined. Test fixtures were fabricated to study the antenna designed at 4.9 GHz when there was an active solar cell under the antenna. It is found that the solar cell affects the input impedance of the antenna and causes a 2-3 dB gain reduction. Repetitive tests were performed to confirm that the effect from solar cells on the antenna remained the same regardless of the working states of the solar cell, type of cover glass, or the assembly of the solar panel.

“…In order to address this challenge, the use of photovoltaics in communication systems has recently been the subject of much research. In the literature, two types of photovoltaics-antenna integration techniques have been demonstrated involving the autonomous integration of solar cells and microwave antennas [1] and the full integration of these two elements in a self-powered communication system [2][3][4][5][6][7][8], respectively. The first technique consists of autonomous solar powered communication systems and involves using the solar cells as an independent power source operating separately from the antennas.…”

“…The drawback of using solar cells as an RF ground plane is that the radiating element, which is conventionally opaque in structure, is placed upon the solar cell and therefore shading the cell and reducing the solar efficiency of the antenna. This has been addressed in [6,7] and [8] where optical transparency of the radiating patch element has been increased by meshing the patch and making the patch from a transparent conductive material, AgHT-4, respectively. However, special printing equipment is required to be able to apply the meshing technique while the cost of transparent conductive materials is expensive.…”

A SOLAR CELL STACKED SLOT-LOADED SUSPENDED MICROSTRIP PATCH ANTENNA WITH MULTIBAND RESONANCE CHARACTERISTICS FOR WLAN AND WiMAX SYSTEMS

Abstract-In this paper, a novel self-complementary shaped multiple-L slot loaded suspended microstrip patch antenna stacked with a polycrystalline silicon (poly-Si) solar cell is presented for 2.4/5.2 GHz band WLAN and 2.5/3.3/5.8 GHz band WiMAX networks. While the proposed self-complementary shaped multiple-L slot loaded suspended patch enables the propagation of multiple TM mn modes to be present, the poly-Si solar cell works as an RF parasitic patch element in addition to its photovoltaic function. The proposed stacked solar antenna combination topology enables the radiating patch to be easily modified by slot-loading to achieve multiband resonance characteristics and the poly-Si solar cell to operate without being shaded by any RF components of the antenna ensuring an optimum solar operation performance.

“…These designs utilizing optical energy harvesting and data communication typically use solar cells directly as part of the antenna. For example, in [2], a patch antenna is designed using solar cells as ground plane of the patch or [3] uses a solar panel as a slot antenna. These solutions or similar ones are not favorable under the constraint that the antenna structure must work in metal as a patch antenna or a cavity backed slot antenna are not well suited for the integration into a metallic machine tool.…”

This paper presents a hybrid antenna design for an optically powered super high frequency (SHF) radio frequency identification transponder applicable for the integration into metal. The key feature of the antenna is its ability to receive microwave signals at SHF for data communication and optical signals for the power supply of the transponder. The antenna design is based on a circular waveguide which is filled with a bundle of polymer optical fibers to guide light to the photodiodes. In addition, a transition is placed within the circular waveguide to transfer the waveguide mode of the SHF signal into a microstrip mode which is a more suitable structure for the integration of electronic transponder components. This paper discusses the constraints and solutions for the aforementioned combination of SHF microwave and light. The figures of merit of the optical power supply are presented, including considerations of the light distribution and the obtained power as a function of the incident angle and the used polymer optical fiber diameter. Furthermore, the measured gain and return loss of the SHF antenna structure is compared to the simulated results. I . I N T R O D U C T I O NDuring the last few years, radio frequency identification (RFID) applications in general have been significantly growing and especially in the field of electronic article surveillance they have become one of the most important techniques. However, commonly used RFID transponder antennas, typically dipole-like antennas, suffer from performance degradation under the influence of a metallic environment especially when they are placed directly on a metallic surface. For the use of transponders in machine tools e.g. a miller, it is desirable to integrate them into that tool, as a transponder placed on the surface can be damaged easily under mechanical stress. The usage of an integratable transponder equipped with memory is a very interesting task in the field of machine tool monitoring, providing the ability to trace the product life of the tools. Hereby, the range of application is mainly limited by the transponder size, as the integration of the transponder mechanically weakens the machine tool and the volume needed for the integration of the transponder is sometimes not available. Since the antenna dimensions and the carrier frequency are reciprocally proportional, the antenna is designed to work in the Industrial, Scientific and Medical (ISM) band at 24 GHz.Owing to the high operating frequency and therefore increased free space attenuation, a classical passive RFID transponder supply concept based on a rectifier [1] does not yield enough supply power. Thus, hybrid antenna concepts are necessary to overcome this limitation. These designs utilizing optical energy harvesting and data communication typically use solar cells directly as part of the antenna. For example, in [2], a patch antenna is designed using solar cells as ground plane of the patch or [3] uses a solar panel as a slot antenna. These solutions or similar ones are not favorabl...
