CONCLUSION Micro strip antennas have become a rapidly growing area of research.Their potential applications are limitless, because of their light weight, compact size, and ease of manufacturing.One limitation is their inherently narrow bandwidth.However, recent studies and experiments have found ways of overcoming this obstacle.
A variety of approaches have been taken, including modification of the patch shape, experimentation with substrate parameters, Most notably mobile communication systems where many frequency ranges could be accommodated by a single antenna.We here design simple and low costlier patch antenna for pervasive wireless communication by using different patch length.The transmission line model seems to be the most instructive in demonstrating the bandwidth effects of the changing the various parameters.When the proposed antenna design on a 31mil RT DUROID 5880 substrate from Rogers-Corp with dielectric constant of 2.
