Frequency Reconfigurable CPW-Fed Hybrid Folded Slot/Slot Dipole Antenna

Abstract

This work presents the design of a frequency reconfigurable probe fed finite-ground co-planar waveguide (FGCPW) fed hybrid dual (or twin) slot dipole-folded slot antenna that reconfigures in frequency to enhance the overall bandwidth of the structure. The operation of the antenna is a function of the combined resonant behavior of the two structures as it switches between configurations. In the current configuration, two surface mount switches, hard wired for proof of concept, are used to switch between the two configurations. This approach to reconfiguration (demonstrated on a basic geometry) may be implemented on more complex antenna designs to further enhance their operation.
