Date of Defense 2003-12-08 Availability unrestricted AbstractReconfigurable 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.
