Design of CPW-Fed High Rejection Triple Band-Notch Uwb Antenna on Silicon Substrate With Diverse Wireless Applications

In this paper, a CPW-fed circular patch UWB-extended bandwidth antenna is proposed which is fabricated and characterized on silicon.The proposed antenna covers fractional bandwidth of 132.08% with high rejection triple band-notch characteristics [WiMAX(3.30GHz-3.80GHz)/WLAN(IEEE802.11a/h/j/n 5.15 GHz-5.35GHz, 5.25 GHz-5.35GHz, 5.47 GHz-5.725GHz, 5.725 GHz-5.825GHz)/X-band downlink satellite communication system (7.25 GHz-7.75GHz)].Gain and efficiency of the proposed antenna in the entire bandwidth vary between 3.96 dBi-10.98dBi and 84%-95%, respectively.Also, group delay in the entire operating band is ≤ 1.0 ns.Furthermore, the proposed antenna exhibits good dipole like radiation pattern in E-plane and omnidirectional pattern in H-plane with small dimension of 20 × 20 × 0.5 mm 3 .
