Most of the research in the field of ad hoc network is limited to stand-alone isolated networks. In order to facilitate the users with the huge pool of resources together with the global services available from the Internet and for widening the coverage area of the MANET there is a growing need to integrate these ad hoc networks to the Internet. For this… (More)
This paper presents the design and development of linearly polarized microstrip antenna (MSA) arrays (108 elements and 296 elements) at the centre frequency of 35.5 GHz. Both corporate and series feed networks are used in these arrays to realize non-uniform excitation distribution to obtain high gain and moderate side lobe level (SLL). For the 108 element… (More)
Wireless sensor network (WSN) is a special kind of ad-hoc network consists of battery powered low cost sensor nodes with limited computation and communication capabilities deployed densely in a target area. Clustering in WSN plays an important role because of its inherent energy saving capability and suitability for highly scalable network. This paper is an… (More)
A compact suspended planar patch antenna is presented for microwave imaging sensor array designed at ISM Band. The radiating patch of the compact suspended antenna is placed at a height of 5mm considering air dielectric substrate (ε<sub>r</sub> = 1.001). The antenna is fed by a coaxial probe and single shorting post is placed in its lower left corner… (More)
Most significant Balance of System (BOS) unit for monitoring health of a Photovoltaic (PV) system is the power Conditioner unit. Here, authors propose incorporation of an additional controller unit for monitoring all possible states of the Battery-bank leading to an enhanced energy security mechanism for small decentralized PV applications.
The linear analysis of digital phase locked loop (DPLL) does not include finite precision arising owing to the limited size of register or memory for processing or storing the coefficients or data in most of the literatures. This truncation in word length results a serious degradation in DPLL performance. This paper addresses a problem where a truncation… (More)
—Electromagnetic wave absorption inside a human body is investigated. The human body has been modeled using 3D voxel based dataset considering different electrical parameters. At GSM 900 band, Specific Absorption Rate (SAR) induced inside the human body model exposed to a radiating base station antenna (BSA) has been calculated for multiple number of… (More)
