Abstract :
A new type of CPW-fed dual-annular-slot antenna operated in the 5.8 GHz band is introduced. Both the inductive and the capacitive configurations are presented. The design considerations of the antennas are discussed. Measurement shows that the antennas have a wide bandwidth of 16% with a peak gain of 5.4 dBi for the inductive configuration and 7.8% with a peak gain of 4 dBi for the capacitive configuration.
