Abstract

In this paper, a triple-band printed dipole antenna using parasitic elements is proposed for multiple wireless services. The proposed antenna is designed and experimentally analyzed at the PCS, IMT-2000, and ISM bands. To achieve triple-frequency operation, the proposed antenna has a printed dipole structure with two parasitic elements, which act as additional resonators by coupling from the driving dipole antenna. From the measured results, the resonant frequencies of this antenna are 1.79, 2.03, and 2.41 GHz, and the measured impedance bandwidths are 90 MHz (1760-1850 MHz), 210 MHz (1930-2130 MHz), and 30 MHz (2400-2430 MHz) for VSWR < 2. The measured gains are 2.14, 0.9, and 0.5 dBi, respectively. The antenna parameters for triple-band operation are investigated and several antenna characteristics are discussed.
