Abstract
Reconfigurable antennas represent a recent innovation in antenna

design that changes from classical fixed-form, fixed-function antennas

to modifiable structures that can be adapted to fit the requirements

of a time varying system. Advances in microwave semiconductor

processing technologies have enabled the use of compact, ultra-high

quality RF and microwave switches in novel aspects of antenna design.

This dissertation introduces the concept of reconfigurable antenna

bandwidth control and how advances in switch technology have made

these designs realizable. Specifically, it details the development of

three new antennas capable of reconfigurable bandwidth control. The

newly developed antennas include the reconfigurable ring patch, the

reconfigurable planar inverted-F and the reconfigurable parasitic

folded dipole. The relevant background work to these designs is

described and then design details along with computer simulations and

measured experimental results are given.
