A Metal Solar Cell Antenna Array

This paper proposes an all-metal solar cell antenna array. It consists of leaf-shaped metal radiators, feeding probes, a metal ground, a solar cell and ground probes. The all-metal solar cell antenna array consists of 36 antenna units with rectangular grid. The AVSWR is less than 2 in the range of 3.2~5.2GHz, with bandwidth about 63%. Moreover, it has a two-dimensional phase scanning capability of ±45°. This designed integrates solar cell and antenna, it may be used to design a green communication system.
