LTE Antenna’s Parameter Enhancement for Mobile Communication Applications

Long Term Evolution (LTE) is a fourth generation standard for wireless communications of high data speed at the user terminal. This evolved technology needs a cutting edge system component to be designed for the node B (Base station) and the user mobile device. In any wireless device, the performance of radio communications depends on the design of an efficient antenna. The objective of this research work is to design printed antennas suitable for use within LTE mobile terminals. To satisfy the antenna size of LTE devices, meander line technology is used to reduce the resonant length of the antenna. Professional design software (HFSS) is used to design and optimize a 0.78 and 2.5 GHz single element Meander Line Antenna and E-shape MLA as anew shape to give an enhancement the bandwidth and the small gain. We used in this thesis two techniques: the first technique is parametric study where study each variable in the antenna then study the effect each of them on the antenna, after that go to other type and make the work until finish all the variables. The second technique is optimization technique using Genetic Algorithms. This technique can be effectively used in the design of various complex antenna and millimeter dimension circuits, where the performance of this technique to design the antenna is a good precision design of antenna elements for low and high frequency applications. MATLAB codes were written to determine the resonant frequency and the bandwidth for each study in this thesis
