Design and Analysis of Multiband Frequency Reconfigurable Microstrip Patch Antenna Structures For Wireless Applications

摘要

The comparative analysis of reconfigurable microstrip patch antenna is presented in many papers. In orders to satisfy the requirements' for the advanced system in modern wireless applications, different multiband and reconfigurable antenna have been proposed and investigated in the past years. In proposed idea different shapes of antenna were presented (such as E & U shape and Circularly polarized shape) especially to achieve multiple frequencies for various wireless applications. This antenna is smaller in size and can build on a double side of the printed circuit board or stamped from thin sheet metal. Similarly microstrip patch antenna for different frequency range will be implemented in order to meet the demand (like bandwidth or else to reduce narrow band) in emerging communication field with respect to size, cost and weight of the antenna. Design of rectangular multiband microstrip patch antenna includes the analysis of antenna parameters such as bandwidth,gain,return loss etc. these parameters have to be analysed using certain dimensions. This antenna can be used for different applications.
