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.
