An aperture coupled stacked Sierpinski gasket fractal antenna with a defected ground structure is proposed in the current article for ultra wide band (UWB) and wireless local area network (WLAN) applications. The radiating structure is formed of two Sierpinski gasket fractal patch antenna layers on two layers of FR4 substrate stacked one over the other. This stacked structure is fed by a third (bottom)...
This article presents a multilayer stacked sierpinski gasket equilateral triangle fractal antenna with proximity feeding. The two layers of fractals excite two resonant frequencies of the IEEE802.11a/b bands. The antenna is fed using proximity feeding mechanism with a defected ground structure (DGS) using a *** shaped slot in it. This helps in exciting the third resonant frequency of the C band. The...
The goal of this paper is to use defected ground structures (DGS) in microstrip planar array antenna for multiband band operation. The DGS structures are introduce to improve the performance of planar array antenna in terms of return loss, gain, directivity and voltage standing wave ratio. The array of two by two (2×2) planar array antenna with inset feed based on quarter wave impedance matching technique...
Performance of Micro strip Patch Antenna with three different configurations of substrate materials has been analyzed and presented in this paper. It is shown that the Micro strip Patch Antenna with square EBG Structure achieve a high gain and large Bandwidth as compared to conventional Micro strip Patch Antenna. Placement of EBG Superstrate from the patch of Antenna is critical so distance between...
