A CPW Fed Monopole Antenna with Uniplanar EBG & Rhombic SRR

In this book, the design and analysis of a compact coplanar waveguide (CPW) fed multiband monopoleantenna loaded with electromagnetic bandgap structures (EBG) is presented. By placing split ring resonators (SRR) the proposed antenna study extended for operating over the frequency range of Bluetooth / IMT– E (2.4–2.484 /2.5-2.65 GHz), (WLAN 802.11 group with 5 different frequency ranges 2.4 GHz, 3.6 GHz, 4.9 GHz, 5 GHz, 5.9 GHz) for personal wireless communication systems. Other frequency bands beyond Ultra-Wideband 11.73 – 12.75 GHz are used for RADAR and fixed satellite communication systems are also covered under the designed antenna model. The introduction of Uniplanar EBG structure in combination with Rhombic SRR resulted in significant decrease of surface waves, thereby providing an increase in gain of proposed antenna compared with simple monopole.
