Design of a CPW-fed Compact Dual Band (UWB/Bluetooth) Integrated Antenna with Single Band Notched Features
A concise, low-profile, and planar Ultra-Wide Band and (UWB) Bluetooth integrated antenna with dual band (3.4/5.5) rejected features is proposed. The antenna works dual band operation covering 2.4 - 2.484GHz (Bluetooth) and 3.1 - 10.6GHz (UWB) frequency band with single band WLAN (5 to 6GHz) rejected features. It is fed by the CPW and built on a substrate FR-4. By cutting C-shaped slot in the patch band-rejected filtering property for WLAN (Wireless LAN) band is achieved. The calculated and simulated results are agreed fine. The antenna shows acceptable gain uniformity with stable omnidirectional radiation patterns across the UWB and Bluetooth integrated bands. The average group delay is around of 0.2ns across the UWB frequencies.
