Compact printed antennas are an essential need of modern wireless world. An UWB planar aperture antenna for various wireless applications is presented in the literature. This antenna covers a wide range of frequencies from 2.14 GHz to 6 GHz. In this whole range of frequencies S11 is under −10 dB. The designers designed a bowtie shaped aperture from the thin copper layer fed by CPW feed line aperture...
A miniaturized ultrawideband (UWB) microstrip-fed patch antenna on FR4 substrate is proposed. For miniaturization of UWB antenna resonating 3.1-10.6 is designed Ghz using fractal approach of the radiating edge. A miniaturization of active patch area and antenna volume is achieved up to 45.33% and 31.2% respectively. The proposed miniaturized UWB antenna with metamaterial loading and slotted ground...
A triple band-notched ultrawideband (UWB) trapezoidal shape microstrip-fed patch antenna on FR4 substrate is proposed. Notch stop bands are achievedaround the WLAN (5.15–5.25 GHz), WiMAX (3.3–3.8GHz) and X-band (7.9–8.4 GHz) by etching one elliptic single split-ring resonator (ESSRR) from radiating patch and by placing two squaresingle split-ring resonators(SSSRRs) of different dimensions near feedline,...
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...
In this paper, a novel compact ultra wideband (UWB) frequency-band reconfigurable antenna with seven switchable states including an ultra wideband (UWB) state, three narrowband states, one dual-band state and one triple band state is presented. In ultra wide band (UWB) state, antenna yields an impedance bandwidth of 2.54 to 11.71 GHz with return loss S11
