ABSTRACT
A detailed study on the various next generation nature inspired geometry antennas
i.e. fractal antennas is performed. Mainly four types of printed fractal antennas i.e.
Sierpinski Carpet, Quasi Koch Fractal, Mix fractal and Sierpinski Gasket Fractal
are designed using 3D FEM based solver (Ansoft HFSS), which are basically
variants of Patch antenna. Maximum iteration is three and these antennas are fed
using three basic techniques Transformer Feed, Inset Feed and..............etc

Fractal Antennas

There has been an ever-growing demand, in both the military as well as the commercial sectors, for antenna designs that possess the following highly desirable attributes: 1. Compact size 2. Low profile 3. Conformal 4. Multi-band or broadband

There are a variety of approaches that have been developed over the years, which can be utilized to achieve one or more of these design objectives. Recently, the possibility of developing antenna designs that exploit in some way the properties of fractals to achieve these goals, at le..............etc

Plasma antennas are radio frequency antennas that employ plasma as the guiding medium for electromagnetic radiation.

The concept is to use plasma discharge tubes as the antenna elements. When the tubes are energized, they become conductors, and can transmit and receive radio signals. When they are de-energised, they revert to non-conducting elements and do not reflect probing radio signals. Plasma antenna can be Steered electronically. Another feature of the plasma antenna is that it can be turned off rapidly, reducing ringing ..............etc

different antennas have been developed and investigated for RKE (Remote Keyless Entry) and related automotive applications. These antennas include small printed-on-dielectric passive and active, printed-on glass, and whip-splitter types. Key antenna parameters-including size, performance, antenna shape-are proposed, investigated,The characteristics of small antennas taking into account the often significant effect of the cable length and direction position have also been investigated and are presented; solutions are also presented that eliminat..............etc

Abstract
Virtual Cellular Networks (VCN) are an attractive type of adaptive
wireless communication architecture for propagation- and
coverage-limited environments. In this paper, we investigate the
advantages of combining a VCN and multiple receiving antennas
for the downlink resulting in a MIMO system. Several ways
to combine the signals with different levels of complexity are
presented. In the most complex case, we show that it is possible
to add coherently the contribution of each antenna in a virtual
cell..............etc

Abstract
In this paper, we consider the issue of efficient broadcasting in mobile ad hoc networks(MANETs) using network coding and directional antennas. Network coding-based broadcastingfocuses on reducing the number of transmissions each forwarding node performs in the multiplesource/multiple message broadcast application, where each forwarding node combines some ofthe received messages for transmission. With the help of network coding, the total number oftransmissions ..............etc

his paper mainly concentrates on use of smart antennas in mobile communications that enhances the capabilities of the mobile and cellular system such a faster bit rate, multi use interference, space division multiplexing (SDMA),increase in range, Multi path Mitigation, reduction of errors due to multi path fading and with one great advantage that is a very high security. The signal that is been transmitted by a smart antenna cannot tracked or received any other antenna thus ensuring a very high security of the data transmitted.
