In this literature a new design of printed antipodal UWB vivaldi antenna is proposed. The design is further modified for acquiring notch characteristics in the WLAN band and high front to backlobe ratio (F/B). The modifications are done on the ground plane of the antenna. Previous literatures have shown that the incorporation of planar meta-material structures on the CPW plane along the feed can produce...
In this paper a modified compact CPW fed printed monopole antenna is presented. Modified double circular shaped monopole antennas with different type of feedings are proposed to achieve directional radiation characteristics and high front to back lobe ratio (F/B) for various applications. The proposed antenna covers the ultra-wideband (3.3 GHz–10.6 GHz) and a part of the license free super wideband...
