Circular patch antenna: Effective analysis for various patch diameter sizes

This paper present the effect of changing the patch diameter on directivity pattern of a linearly polarized micro strip patch antenna. The antenna discussed here has been fabricated on the base of Benzocyclobutene Di-Electrics with di-electric permittivity of et 2.65, simulated with centre frequency of 2.4ghz which makes it suitable for wireless gps, satellite communications. antenna designed have varying size of radius with other significant parameters kept constant in the process of simulation and study.
