Abstract :
The design of coplanar waveguide fed single annular-ring slot antenna for obtaining dual-frequency operation is presented. This is achieved by introducing a back-patch to perturb the slot´s electric-field distribution. Details of the proposed designs are described, and experimental and theoretical results are presented and discussed.
