By combining GA with FDTD, integrated multiband antenna designs can be generated at arbitrary frequencies of interest. These antennas designs can use an arbitrary shape. This paper presents the optimized design of a dual band GSM microstrip monopole antenna. It is impedance matched extremely well in the GSM frequency bands of 890-960 MHz and 1850-1...

In this paper a new type of a wideband aperture-coupled microstrip antenna is presented. The antenna is modelled as a 2.5 D structure, and is optimized using a genetic algorithm (GA). In addition to the radiator shape, the feed and the coupling slot dimensions are also included in the optimization process. The impedance bandwidth corresponding to V...
This paper investigates the hand-hold implications on the electromagnetic coupling between human head and cellular phones. FDTD-method has been used to evaluate both the antenna performance and the induced SAR in head as caused by different phone models held at different hand positions. Bar-type and clamshell-type phones having external and interna...

Researchers have proposed applying optimization techniques to improve performance of microstrip antennas (MSAs) in terms of bandwidth, radiation characteristics, polarization, directivity and size. The drawbacks of the conventional MSAs can be overcome by optimizing the antenna parameters while keeping a compact configuration. Applying a global optimizer is a better technique than using a local optimizer or a trial and error method for performance enhancement. This paper discusses genetic algorithm (GA) optimization of microstrip antennas presented by the antenna research community. The GA optimization procedure, antenna parameters optimized by using GA and the optimization objectives are presented by reviewing the literature. Further, evolution of GA in the field of MSAs and its significance are explored. Application of GA optimization to design broadband, multiband, high-directivity and miniature antennas is demonstrated with the support of several case studies giving an insight for further developments in the field.
