Study of superstrate cover annular slot antenna array at 10 GHz

摘要

A comparative study of a low dielectric based four element linear array of annular slot antenna has been made with and without superstrate cover at 10 GHz. The far-zone field expressions are obtained using vector wave function approach and analytical technique of microstrip antennas. The radiation properties of both the cases are obtained for two modes in free space. The results obtained are suitable for mobile communication systems.
