Influence of solar heating on the performance of integrated solar cell microstrip patch antennas

摘要

The integration of microstrip patch antennas with photovoltaics has been proposed for applications in autonomous wireless communication systems located on building fac.ades. Full integration was achieved using polycrystalline silicon solar cells as both antenna ground plane and direct current power generation in the same device. An overview of the proposed photovoltaic antenna designs is provided and the variation characterised of the electromagnetic properties of the device with temperature and solar radiation. Measurements for both copper and solar antennas are reported on three different commercial laminates with contrasting values for thermal coefficient of the dielectric constant.
