This paper highlights the proposed design for a Dual band Fractal Monopole antenna using a Circular Split Ring Resonator and fed through a 50Ω inset feed over the Rogers RT/Duroid 5880tm substrate for the Wi-Fi and Wi-Max applications. The proposed antenna resonates at Wi-Fi frequency (2.4 GHz) and the Wi-Max frequency (3.5GHz). The proposed Antenna resulted in a Gain of 0.14dBi for 2.4GHz and 2.9dBi...
Mutual coupling is a critical issue in antenna elements is placed in the form of array between the antenna elements. In the present work Jerusalem cross periodic structure is proposed as an effective solution for reducing mutual coupling in a micro strip array antenna with more than one element. This structures have been Applied between the patches have been Simulated and verified with practical results.
A T-shaped Printed monopole antenna with low profile and fed by 50Q inset feed techniques on FR4 substrate is proposed which finds application in Wireless Local Area Network (WLAN). This project work aims in designing a compact uni-planar Antenna with high gain for Wireless applications using inset feed technique. This frequency 2.4GHz (2.256–2.687 GHz) shows that antenna is suitable for WLAN application...
A (2×2) microstrip patch antenna array (MSPAA) is designed at 10 GHz., for low radar cross section (RCS) outside the operating band of the antenna in the frequency band from 16 GHz. to 26 GHz. The conventional ground plane of the MSPAA is modified by using a hybrid ground plane comprising Jerusalem cross slot (JCS) frequency selective surface (FSS) elements in a square grid.

A novel Ultra Wide Band (UWB) dielectric Radar Absorber (RA) with weight and thickness constraints is presented in this paper. Radar reflectivity of − 10 dB (minimum) is realized in the frequency band from 2 GHz. to 32 GHz, for normal incidence. The panel type RA comprises four lossy frequency selective surface (FSS) layers, each based on circular patches in skewed grid lattice backed by RF transparent...
The objective of this paper is to design and to analyze the performance of Electromagnetic Band-Gap (EBG) antenna for wireless application through simulation.

The V-BLAST (Vertically-layered Bell Laboratories Layered Space-Time) algorithm is a multilayer symbol detection scheme. The proposed work focuses on V-BLAST technique with a Multiple Input Multiple output (MIMO) technology followed by receiver detection techniques like Zero forcing (ZF), Minimum Mean Square Error (MMSE) with back substitution SIC (Symbol Interference Cancellation). The proposed methodology...
Steered Patch arrays with a dielectric lens for collimation are well suited for vehicular applications due to their small form factor and effective sealing ability. In this paper we present an accurate analytical formulation of a patch array radiating in the presence of a hemispherical Dielectric lens based on spherical modal expansion (SME) and experimentally demonstrate an increase in directive...
Multiple Input Multiple Output (MIMO) is a radio communication technology or RF technology that is being mentioned and used in many new technologies these days. The capacity of such a system depends on transmit and receive antenna strategies. The MIMO capacity scales roughly and linearly with the number of Transmitter and Receiver antennas. The two core approaches have been adopted to study the system...
