Design and Analysis Of X Band Microstrip Antenna for Broadband Communication

Abstract

The increasing demand of high data rate and simultaneous reduction in size of the device has led to increase need of new designs in multiple applications of latest wireless communication systems. The evolution of micro strip antennas started in the last quarter of the twentieth century. The acceleration in research and progress in the field of micro strip antenna has been attributed due to prominent their features like low weight, manufacturing ease, flexibility and adoptability with micro wave circuits over other types of antenna.The present thesis deals with the design and fabrication of a specific, simple and compact square shaped micro strip antenna. In view of this the effects of dimension of substrate and feed line on the bandwidth have been analysed. The study of the single design antenna has been done before fabricating antenna. The design patch antenna was initially in rectangular shape and it has been intended to square shape to simplify the fabrication and geometry symmetrisation. In order to validate the work, simulated results and measured results of the fabricated antenna has been compared.The features, advantages and limitations for the various types of feeding technique are also discussed. An effort has been made to develop a mathematical modelling for micro strip antenna with strip line feeding technique as formulated using Ohm s law. A partial differential equation is obtained from the above derived mathematical modelling that is solved by using most advanced and recent approach viz. Reduced Differential Transformation method (RDTM) . Numerical instances based on one and two dimensional wave equation are illustrated to check the accuracy, efficiency and convergence of the RDT method that suggests that the RDTM can efficiently use for solving wide range of problems arising in circuit theory, RF field, and science and communication systems fields.and#8195; newline
