Integrated 23-Cm and UWB antenna with dual notched characteristics

An integrated 23-Cm and Ultra Wide Band (UWB) Antenna is proposed, which has dual band notched characteristics. It is designed for avoiding the interference of frequencies 4.7 GHz and 6.95GHz. Antenna impedance bandwidths are 100MHz (1.2GHz-1.3GHz) and 8.7GHz (3.2GHz-11.9 GHz) that cover the 23-Cm band and entire UWB band. The VSWR in the band notched frequencies are 14 and 5.9 respectively. Measured results are presented to validate the antenna performances. Antenna is designed and fabricated on FR4 substrate with dielectric constant 4.4 and height 1.59mm.
