Abstract
This seminar describes three different antenna systems for mobile vehicle applications. The antennas are either patches or derivatives in all cases. The first is a dual-band telephone antenna with a low profile and wide bandwidth. Operating at 900 MHz and 1800 MHz, with a VSWR of better than 1.7, it is a hybrid construction combining a monopole with a top-loading patch shorted to the ground-plane. Extra-shorted pins provide the upper frequency band coverage. It provides monopole radiation characteristics and can be hidden under a plas ....etc

Small Fractal Antennas

1 Problem
Antennas for hand-held communication devices are necessarily small, and typically use wavelengths
that are large compared to the size of the antenna. This typically implies that
the magnitude of the antenna reactance X (= imaginary part of the antenna impedance) is
large compared to that of its radiation resistance Rrad (which is related to the time-average
radiated power P and the peak current I0 at the feedpoint by P = I2
0Rrad/2), so that it is
challenging to build an effective imped ....etc

the new world of Plasma Antennas



Antenna technology

Physically, an antenna is an arrangement
of one or more conductors, usually
called elements. In transmission,
an alternating current is created in the
elements by applying a voltage at the
antenna terminals, causing the elements
to radiate an electromagnetic field. In
reception, the inverse occurs. An electromagnetic
field from another source
induces an alternating current in the elements
and a corresponding voltage at
....etc

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
