Planar Monopole Ultra Wide Band Antenna on Silicon with Notched Characteristics

The design and development of Ultra Wide Band (UWB) antenna on silicon substrate is presented in this article. Planar monopole antenna having circular radiating patch, excited with 50 ? co-planar waveguide transmission line is chosen here. Slots are incorporated in the radiation patch to achieve band-notch characteristics at two distinct bands for WiMAX (3-4 GHz) and WLAN (5-6 GHz) applications. Both single and dual-notch banding concepts are presented. A close analogy is achieved between measured and simulated results after fabricating the finalized topologies on high resistive silicon substrate. Effects of fabrication/assembly on performance of the final device are also discussed in this article.
