A Dual-polarized Antenna with Solar Cell Array for Low-carbon Communication

A 5×5 solar cell array is integrated with an antenna radiation aperture for 5G low-carbon communication. Leveraging the distinct properties of the inductor in DC and RF bands, surface-mounted inductors are incorporated into the circuit of the solar cell array, ensuring both DC connectivity and optimal dual-polarization performance. This dual-function design achieves a dual-polarized broadband antenna with DC power generation. The antenna demonstrates a high port isolation of more than 30 dB, with a simulated -10 dB bandwidth covering 5G target bands from 3.3 GHz to 5 GHz. The simulated gain is more than 8.6 dBi for two polarizations. This design utilizes a solar cell array as the radiating structure for 5G broadband antennas, reducing the cost and complexity of this dual-function device, and offering an attractive solution for future low-carbon communications.
