In this paper the design issues of compact genetic microstrip antennas for mobile
applications has been investigated. The antennas designed using Genetic Algorithms
(GA) have an arbitrary shape and occupies less area (compact) compared to the
traditionally designed antenna for the same frequency but with poor performance. An
attempt has been made to improve the performance of the genetic microstrip antenna by
optimizing the ground plane (GP) to have a fish bone like structure. The genetic antenna
with the GP optimized is even better compared to the traditional and the genetic antenna.

Negative magnetic permeability media
(NMPM) can be built up by using small resonant metallic
particles like Split ring resonator (SRR) which has very
high magnetic polarisability. A group of these particles
shows a negative permeability region near and above the
resonant frequency. The continuous medium parameters
describing the SRR array can be predicted from their
individual electromagnetic behavior near the resonances.
The paper presents an optimizing software using Genetic
Algorithm (GA) to design an edge coupled two ring SRR
for a particular frequency

Abstract:
A method for simultaneously enhancing the bandwidth
and reducing the size of microstrip antennas (MSAs) using a modified
ground plane (GP) has been proposed with design formulas. A combshaped
truncated GP is used for this purpose. This method provides an
overall compactness up to 85% for proximity-coupled MSAs in the
frequency range of 900 MHz–5.5 GHz with an improvement inbandwidth up to seven times when compared with the conventional ones

A compact coplanar waveguide (CPW) fed uniplanar antenna for Quad-band applications is presented.
The Quad-band operation is realized by imposing various current paths in a modified T-shaped radiating
element. The antenna covers GSM 900, DCS 1800, IEEE802.11.a, IEEE802.11.b and HiperLAN-2 bands and
exhibits good radiation characteristics. This low profile antenna has a dimension of 32mm×31mmwhen
printed on a substrate of dielectric constant 4.4 and height 1.6mm. Details of design with experimental
and simulated results are presented
