The present work aims to analyze the performance of a newly designed graphene-based patch antenna by varying the chemical potential in graphene sheet, using the CST Microwave Studio ® software. This study mainly seeks to discuss and assess the advantage of using graphene, instead of copper, as the radiating patch. It should be noted that graphene is a new material that possesses unique properties. Its parameters are optimized for the purpose of introducing it in satellite technology.

The use of graphene as a radiating patch of space technology applications, where a polygonal graphene patch antenna element is designed by the CST Microwave Studio ® software with Taconic RF-41 substrate to resonate in the satellite bands.

Analysis of a graphene patch sheet by a variation in the chemical potential to ensure operation in a space environment.

The increase in the chemical potential for a graphene patch antenna has shown a prominent increase in the values of the gain. A new contribution, by the combination of the antenna performance improvement techniques and the use of graphene as a radiating patch of space technology applications.

This paper aims to explore the option of Sharī’ah-compliant microfinance as a viable alternative to many previous approaches adopted by the Nigerian State in tackling the menace of poverty in the land. In spite of many poverty alleviation policies and interventions of the past three decades, millions of Nigerians still live in abject poverty, while thousands of university graduates roam the streets looking for jobs. Many unemployed Nigerians with good business ideas are usually discouraged by the alarmingly high interest rate charged on start-up capitals by local banks.

To achieve its objective, this paper used both analytical and qualitative methods after thoroughly examining many relevant literature and empirical works. The study explores four Sharī’ah tools for the implementation of the proposed scheme, to wit: musharakah, mudharabah, zakat and waqf.

The study finds that the suggested Sharī’ah tools are viable and sustainable in lunching microfinance projects in the Nigerian context. The paper further argues that exploring Islamic non-interest microfinance options will guarantee the financial inclusion of a large percentage of Nigerians, pursuant to the Constitutional provision on economic rights of the entire citizenry (s.16 of the 1999 Constitution of the Federal Republic of Nigeria, as amended).

The paper identifies a yet-to-be explored viable option, with great potential not only in enhancing government policies for poverty alleviation but also in assuring a large percentage of the citizens of financial inclusion.
