Design of 3. 5 GHz Band-Notched Compact Monopole UWB Antenna for Wireless Applications
The Federal Communications Commission (FCC) declared the resolution about the ultra-wide bandwidth of 7.5GHz from 3.1 to 10.6GHz for UWB communication. The WiMAX (3.5GHz) interference free Ultra-WideBand (UWB) antenna with simplex monopole structure is proposed. An attempt of defected coplanar ground plane with the use of open-ended half wavelength L-shaped slot and stepped pentagonal radiating patch have been made for pure and frequency notched UWB operation with compact size of 32x22x1.6mm cube. The full UWB and band-notched designs are discussed in detail along with VSWR curves, surface current distribution and radiation patterns.
