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.

Antennas and Propagation Society International Symposium, 2008. AP-S 2008. IEEE
A compact microstrip multiband antenna on a
modified ground plane which can operate over the bands starting
from 900 MHz to 5.35 GHz which includes the GSM (880-960)
GPS (1568-1592 MHz), DCS (1710-1880 MHz), and PCS (1850-
1990 MHz). UMTS (1920-2170 MHz), IEEE 802.11 b/g (2400-
2484) and WLAN IEEE 802.11a band (5.15-5.35) is reported in
this paper. The overall dimension of the antenna is 33 x 33 mm2
including the top patch with a dimension 22 x 22 mm2. The
experimental results of the antenna are presented in this paper.
The results confirm that the antenna exhibits wide band
characteristics and covers 7 bands of operation

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
