Optimization Of Patch Size Of Fractal Hybrid Antenna For Gps Application

In this paper we propose the optimization of patch size for a fractal hybrid antenna that can be used in GPS applications. This project is about two different models namely sierpinski gasket fractal antenna and Koch rectangular fractal antenna. A fractal antenna in general is characterized by space filling and self-similarity properties. These fractal shaped antennas have their own unique characteristic that improves antenna achievement without degrading antenna properties. Due to the space-filling properties of fractal geometry, the proposed antennas are smaller in size than conventional Euclidean-type ones. The antenna designs for dual-band Global Positioning System (GPS) is usually done in the frequency range of 1.2GHz to 1.575GHz. In conclusion, we says that it is possible to optimize the patch size, keeping the operational frequencies same to that of the earlier antenna models, and with a few deviations from the previous results like radiation pattern, bandwidth and gain are computed, it can also be normalized by using advanced manufacturing tools and selection of appropriate materials for better results.
