New Broadband Optimal Directional Gain Microstrip Antenna for Pervasive Wireless Communication by Hybrid Modeling

In this paper, hybrid modeling of Micro-strip antenna is presented. Broadband frequency of operation demonstrated by single geometry .for broadening the bandwidth and maximum directional gain (6.6dBi 8dBi) gap-coupled multi-resonator loaded on parasitic and active patch. The geometry of a single probe fed rectangular Micro-strip antenna incorporating a slot and gap coupled with parasitic and active patch on left side of geometry is studied. After IE3D Simulation we achieved 67% -10dB Bandwidth and analyzed maximum directional gain (6.6dBi 8dBi) between 8GHz 14.5GHz. We investigated concept of strong signal coupling for higher and lower edge of frequency if S=.02λ, we investigated height between active and parasitic patch should be .0525λ and height between parasitic patch itself should be .0525λ. We investigated enhancement in maximum directional gain by using Radom effect concept and stack geometry with one active and two parasitic patches of different dimensions. We achieved 67%BW for VSWR<=2. This proposed antenna is used for satellite, and wireless communication at, X-Band and Ku Band.
