    In this paper, a circular microstrip patch antenna with Defected Ground Structure (DGS) has been analyzed and simulated for the WLAN applications. The proposed antennas have been simulated at 2.45 GHz frequency using co-axial feeding technique. Actually, the authors design two circular microstrip antennas i.e. conventional CMSA and CMSA with...

    Beam Pattern Improvement in CMA Using a Prefilter

    The demand for wireless mobile communications services is growing at an explosive rate; the high demand for 3G services needs increased in system capacity. The most elementary solution would be to increase bandwidth; however, this becomes challenging as the electromagnetic spectrum is becoming increasingly congested. The frequency reuse concept increases...

    Development of OFDM Space Coded Outdoor Wireless Link

    Orthogonal Frequency-Division Multiplexing, or OFDM, is a process of digital modulation that is used in computer technology today. Essentially, OFDM is configured to split a communication signal in several different channels. Each of these channels is formatted into a narrow bandwidth modulation, with each channel operating at a different frequency....

    Location Aided Routing in Mobile Ad Hoc Networks

    A mobile ad hoc network consists of wireless hosts that may move often. Movement of hosts results in a change in routes, requiring some mechanism for determining new routes. Several routing protocols have already been proposed for ad hoc networks. This paper suggests an approach to utilize location information (for...

    A Review on Methodologies of Remote Sensing, GPS and GIS

    Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object. In modern usage, the term generally refers to the use of aerial sensor technologies to detect and classify objects on Earth (both on the surface, and in the atmosphere and oceans)...
