5GHz WLAN band-notched UWB symmetrical slotted PI- notched parasitic planar

In this paper, a new configuration of UWB planar printed compact monopole antenna comprising of symmetrical slots and PI notched with parasitic patches. It has a partial ground plane to achieve an excellent impedance matching to increase the impedance bandwidth. The proposed antenna rejects the 5GHz WLAN band in the frequency range of 5.42–5.74 GHz by introducing PI shaped notch. The simulated results show that the proposed antenna exhibits UWB for 3.52 GHz to 11.06 GHz with −10dB return loss and VSWR < 2. Antenna gain and radiation pattern plots for different frequencies are also investigated. The performance characteristics of the proposed antenna are simulated using HFSS software.
