Design, Simulation, Characterization of Tunable Directive Nanoantennas

Abstract

This thesis was undertaken to study the influence upon gain and directional characteristics caused by numerous array of elements when used in conjunction with the Yagi antenna. The main function of the antenna is to transmit or receive Electromagnetic energy. Antennas are beneficial for a wide range of applications such as point to point communication, radio broadcasting, radar and wireless LAN. However, maximum gain and maximum directivity with low losses are the desired characteristics that are sought. A brief introduction of the basic theory of the Yagi antenna design is given in the first chapter of this thesis. Information on construction of this antenna design is presented accompanied by a comparison of its benefits. In this Thesis, Novel design of ultra-directive microstrip Yagi design (frequency = 2.4 GHz) is simulated and analyzed. We used the FIT technique to obtain the optimized parameters (geometrical parameters) for the Yagi design. Also, the antenna parameters (gain and directivity), and the matching parameters (VSWR and S11) are simulated using the finite integral technique (FIT). The proposed design showed high directivity and high gain
