Mutual coupling analysis of dielectric coated microstrip antennas mounted on the cylindrical surface with varying inter element spacing

Microstrip patch antenna in wireless communication is gaining importance as powerful technological trend. This paper presents design and simulation of a dielectric coated rectangular microstrip patch array antenna conformed to the cylindrical surface for many wireless applications. The conformal rectangular microstrip patch antenna array is analyzed using HFSS and also made a comparison by varying the inter element spacing between the two antenna element which shows interesting results of mutual coupling, return loss etc. Also, the obtained results of mutual coupling between the two element patch antennas arrange in E-plane configuration gives better result than H-plane configuration.
