研究目的
To design a broadband coplanar waveguide (CPW)-fed monopole antenna integrated with an organic solar cell (OSC) for Ku band satellite communication, allowing for 100% insolation of the OSC to improve antenna performance.
研究成果
The proposed CPW-fed monopole antenna integrated with an OSC achieved a 3 GHz broadband in the Ku band and a realized gain enhancement of about 6.30 dB, making it suitable for fixed-satellite-services (FSS) operating in the 11.7 to 12.22 GHz band. The design allows for 100% insolation of the OSC, improving antenna performance.
研究不足
The study was limited by the unavailability of OSC fabrication facilities, leading to measurements being conducted without the solar cell. This may have affected the comparison between simulated and experimental results.
1：Experimental Design and Method Selection:
The antenna was designed to integrate with an OSC for 100% insolation, using a CPW-fed monopole antenna structure. The design was simulated using CST microwave studio based on the finite integration technique (FIT).
2：Sample Selection and Data Sources:
The antenna was fabricated using an LPKF prototyping PCB machine, and measurements were taken using an Agilent PNA-L N5234A vector network analyzer.
3：List of Experimental Equipment and Materials:
LPKF prototyping PCB machine, Agilent PNA-L N5234A vector network analyzer, IS680 substrate, copper metal for the antenna, and an OSC composed of ITO electrode, P3HT:PCBM organic active layer, and aluminum electrode.
4：Experimental Procedures and Operational Workflow:
The antenna was fabricated, connected to a 50 ? SMA connector, and measured for return loss using the vector network analyzer.
5：Data Analysis Methods:
The return loss and gain were analyzed to evaluate the antenna's performance with and without the OSC.
