چکیده مقاله:
Design of a compact and simple coplanar waveguide (CPW) fed printed monopole antenna for ultra wideband (UWB) application with multi band-notches is presented. The bandnotches are created by placing modified U-shaped (MU) slots on the rectangular radiating patch. The narrow width of the MUslots and the low mutual coupling that exists between the slots, allows several slots to be placed on top of each other to create multiple band notches over the UWB range. The proposed antenna has a compact size of 26 × 30 mm2. Return loss and radiation characteristics of the antenna with variousconfigurations of the MU-slots are studied. The antenna with quad-band notches present good rejections over the 3.3-3.6 GHz band (covering IEEE 802.16 WiMAX system), 5.15-5.35 GHz band (WiMAX applications), 5.725-5.825 GHz band (WLAN) and also 7.2 GHz for some C-band satellite communicationsystems. The antenna exhibits omnidirectional radiation coverage with its gain significantly reduced at the notched frequencybands. An equivalent circuit model for the antenna is presented. Measured and simulated results are provided and compared
