This paper describes the parametric study of a novel rectangular planar ultra-wide band antenna (UWB). The proposed design exploits U and T-shaped notches with stairs at two corners on the radiating patch along with stepped microstrip feed. The stairs are also used at the corners of the partial ground plane with a rectangular notch and an(More)
In this paper a full composite fractal antenna, having a modified Sierpinski fractal antenna with 50-Ω microstrip line, used for dual band wireless applications. The S11 parameter and radiation characteristics of the antenna design indicate that a Sierpinski fractal antenna with circular slot having Dual Band frequency bandwidth from 3.8 GHz to 4.4(More)
Design and performance of an ultra-wide band truncated rectangular monopole antenna with band-notched characteristics is presented in this paper. In the proposed antenna, split ring resonator (SRR) is etched inside the truncated rectangular patch of the monopole antenna to achieve band-notch operation. The achieved impedance bandwidth of antenna is from(More)
A dual band circularly polarized single-feed microstrip antenna for wireless communication systems is proposed here and its performance is tested in free space. This modified rectangular microstrip antenna having one protruded curved edge is simulated by using the IE3D simulation software. In between conducting patch and ground plane, designed antenna has(More)
In this paper, a double-layered frequency selective surface(FSS) superstrate was proposed. The unit cell of the proposed FSS consists of a square slot and a Jerusalem cross structure, which are printed on two sides of the substrate. It is designed on the FR4 dielectric substrate with a relative permittivity of 4.8, loss tangent 0.025 and a thickness of 1.6(More)
