A Wideband Ultra-Low-Profile Solar Cell–Integrated Antenna

In this paper, a wideband ultra-low-profile solar cell–integrated antenna with high form factor is presented. A copper indium gallium selenide-based cell was used for the proposed design. The cut rectangular-shaped narrow slit to construct built-in dimensions of 50 mm × 20 0.571 (0.382λo 0.152λo 0.0043λo at 2.28 GHz). area needed achieve only 0.5 18 mm. coaxial-to-microstrip-line transition type feeding structure excite antenna. An RF decoupler circuit also designed under second substrate maintain independent functioning both devices. simulated and measured results are in good agreement. Furthermore, design demonstrated –10 dB impedance bandwidth 42.45% an GHz, maximum gain 2.84 dBi range. addition, has 99.1%, no optical blockage.
