Abstract
Structurally simple and miniaturized ultra wideband (UWB) printed rectangular antenna fed by a coplanar waveguide (CPW) is proposed.Overall dimension of the antenna is as compact as 12 (0.13λ) × 12 (0.13λ) × 1.6 mm3, where λ is the wavelength of the first resonance of the antenna. The main feature of the proposed antenna is its compact size and controllable structure which lead to four different antenna designs. By adjusting the dimensions of the elements of the antenna, notch frequency in different ranges of the UWB can be obtained. The resulting VSWR < 1.5 impedance bandwidth is as large as 11.6 GHz. The antenna presents a stable gain and omnidirectional radiation pattern in its operational frequencies. © 2013 Wiley Periodicals, Inc.
