Nowadays, the mobile phone base stations are situated everywhere due to huge increment in mobile phone usage around the world. However, these mobile base stations have increased the radio frequency exposure level creating issue of health symptoms as the scientific studies has investigated. So a triple band stop frequency selective surface has been proposed with single sided FR-4 substrate inbuilt...
Bandwidth enhancement of a rectangular monopole UWB antenna using M-shaped strip with triple band notched characteristic is presented. Antenna consists of an exciting rectangular patch with two C-shaped and one inverted U-shaped slots along with defected ground plane which is coupled with M shaped strip. By inserting slots to the rectangular patch, three notched frequency bands are achieved. A conceptual...
Bandwidth enhancement of an ultra-wide band swastika slot loaded antenna with band notch characteristic is presented. The antenna consists of an exciting rectangular patch on the front side and a partial ground plane on the backside of the substrate. A swastika shape is etched on patch, by inserting corner slots to the swastika shape, notched frequency band is improved. The simulated impedance is...
This paper presents circular ring and square loop Band reject Frequency Selective Surfaces (FSSs) for dual band WiMax and single band WLAN applications. FSS consist of two square loops with four small square loops in back side & one square loop and circular ring with some slots in front side of the substrate. This FSS designed on the FR-4 dielectric substrate with a relative permittivity of 4...
A reconfigurable circular disc monopole UWB antenna with switchable two notched stop bands is presented. The antenna comprises a circular patch, 50 Ω microstrip feed line, partial ground plane with rectangular notch, and two U-shaped slots with folded arm. Predicated impedance bandwidth 2.78–12.8 GHz with dual notched stop bands 3.25–3.83 and 4.94–5.98 GHz are achieved for WiMAX and WLAN bands by...
Deign and performance of an extremely wideband printed antenna with wireless local area network (WLAN) stop band are analyzed and presented in this paper. In the proposed antenna, an extremely wideband is achieved by modifying ground plane structure and stop band is achieved by inserting split ring resonator (SRR) in the radiating patch. Predicted impedance bandwidth of an antenna is 2.77–21.84 GHz,...
This paper presents the performance evaluation of hybrid network using RIP & IGRP routing protocols for different applications in low load campus network. In this network model, generic LANs models and WLANs are used. In this paper, a simulated environment is created where many applications are in use at a time and their mutual effects thereof. This network model is based on OPNET IT GURU...
