Abstract

This paper presents a multiband planar inverted F antenna for mobile handset applications. The novel idea of F-shaped slot technique is introduced into the conventional rectangular patch antenna for higher GSM frequency. The proposed antenna features rectangular patch antenna for GSM (880-960MHz) band and F shaped slot antenna for DCS (1710-1880MHz) and GSM (1710-1880MHz) bands. The feed for the multiband antenna is Z-shaped feed and coaxial feed. The impedance bandwidth of proposed antenna is 34.1MHz (0.917 GHz-0.9511 GHz) at lower band and 60MHz (1.77GHz-l.83GHz) at upper operating band. The directivity is 2.69dB and 5.69dB at 0.93GHz and 1.8GHz. The radiation pattern is nearly omnidirectional in both the planes. The parametric studies were carried out by High Frequency Structure simulator (HFSS).
