Integration of Antenna Array With Multicrystalline Silicon Solar Cell

Abstract

Abstract-The integration of a low-profile antenna array with a multicrystalline silicon solar cell capable of powering a low power wireless sensor at 2.45 GHz is reported. Lattice bus bars on the cell are exploited to minimize antenna shadows from low profile antennas and transmission lines for a higher output power. The dual inverted-F array improves gain and beam switching enables the array to sweep a wider coverage angle with larger beamwidths compared to other solar integrated antennas.

Transparent Antenna for Green Communication Feature: A Systematic Review on Taxonomy Analysis, Open Challenges, Motivations, Future Directions and Recommendations

“…Due to their special properties, most of the approaches are not applicable for meshed patch antennas combined with solar panels [81]. The integration of antennas with silicon solar cells of amorphous (a-Si) and crystalline (c-Si) was reported although minimizing antenna footprints and solar shadowing related designs still pose as challenges [92]. The fourth category is (4) size, which refers to the limited surface area on small satellites.…”

“…The dual inverted-F array increases gain, while beam switching allows the array to sweep a wider coverage angle with larger beam widths. The transmission line and the cell of a grounding strip with 6 mm width is sufficient to isolate the transmission line from cell lattice, thus displaying improvement in gain, efficiency, and bandwidth [92]. Strained wavy NW networks created by the antennas display higher efficiency of radiation and smaller return loss, when compared to antennas developed by straight NW networks.…”

VHF band spaceborne element rotation angle controlled phased antenna array for SAT‐AIS application

“…As the plate is made of aluminum, it can be considered as a perfect electrical conductor (PEC) ground plane. Additionally, there is no solar shadowing problem because the solar cells and their interconnecting wires are on the opposite side. Furthermore, to increase stability and flexibility, a single channel radio frequency rotary joint slip ring is used, which eliminates the stress on cables and the obstruction to the stepping motor when the elements rotates.…”

Compact Slot Antenna Integrated with a Photovoltaic Cell

“…An effective approach is stacking or overlying to reduce the size and weight. The challenge in this approach is to increase sunlight exposure when the antenna is placed on top of the photovoltaic cell [1][2][3][4].…”
