In this paper, the effect of long-axis length of oval-shaped chassis on the bandwidth potential of GSM antennas is analyzed for the first time. The optimal long-axis lengths for oval-shaped chassis to achieve the maximum antenna bandwidth at 900 MHz and 1800 MHz are obtained. Simulation results show that the optimal long-axis length of oval chassis at 900 MHz is about 155 mm, and at 1800 MHz the optimal lengths are about 80 mm and 165 mm. In addition, a comparison in optimal length between rectangular and oval-shaped chassis is also discussed.
