A compact miniaturized wearable antenna with the appearance of a button on clothing for Wi‐Fi and Wi‐Max applications as well as used for body centric communication is presented. The radiating elements of the antenna are made of copper tape, while the substrate is given a property of transparent acrylic fiber sheet material and fed by a coaxial line through the ground plane. The proposed antenna is...
In this paper, a Co-planar waveguide (CPW) fed wide bandwidth slot antenna is proposed for UWB applications. The antenna consists of a rectangular slot modified at both side of the CPW feed forming two symmetrical step like ground structure. The proposed antenna structure is simulated by using Finite element Method based ANSOFT HFSS electromagnetic simulation software and characterized by return loss,...
In this paper a study on reduction of mutual coupling of two element microstrip antenna array with rectangular split ring shaped defected ground structure(DGS) is presented. The proposed DGS antenna is simulated by MOM based IE3D simulation software. An observation is made on S12 by changing the dimension of the defects and distance between the antenna array elements. The proposed antenna has a maximum...
Compact planar microstrip bandstop filters are introduced here. These filters consist of log-periodic based 3 resonator elements. These defects or slots on the signal plane effecting resonant frequency of the filters due to increment of slow wave factor, which exhibits good bandstop characteristics. The filters can be designed to function in a low frequency to a very high frequency range depending...
