Integrated dual band GSM microstrip monopole using GA and FDTD

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 1850-1990 MHz and the return loss is less that -20 dB at all frequencies in the bands of interest. The antenna shows an extremely flat radiation pattern, with small dimensions which show the ability of the GA to utilize available space to create a compact and relatively broadband antenna.
