[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] In this work, we propose ultra wide band antennas that have small size and simple shapes. The new designs have comparable or improved performance than those of the already available antennas. The thesis aims can be summarized as follows: 1) First, design and fabricate both monopole and wide slot UWB antennas that have simple and small structures and analyze for performance comparable to those of the more complex designs and/or larger size. This part of the thesis can be achieved by modifying already existing antennas, and then utilize them to achieve the second aim of this work, as discussed below. 2) Propose new generalized ways for band notch generation that are suitable for all UWB antennas. This will result in a significant reduction in the optimization parameters. Finally the optimized design will be fabricated to verify the proposed idea. 3) Design and fabricate a new planar monopole switchable antenna that can switch between Multiband/UWB mode that covers the entire indoor applications and Multiband mode that covers some of the outdoor applications for a versatile antenna performance.
