Description
Summary:The development of electrically small antennas plays an important role in the rapidly growing mobile communication market. This work presents a novel design technique for a triple-band small internal antenna which covers the GSM/DCS/IMT-2000 bands. The proposed antenna consists of double shorting posts, feed post, and dual-crossed C-slot patch radiators. A high-frequency structure simulator simulation is employed for optimizing the design parameters, and the simulation results agree with the measured data. The IE3D simulation is also used to obtain the current distribution at the resonant frequencies. The maximum gains at the frequencies 950 and 1860 MHz are measured to be about 1.58 and 1.3 dBi, respectively. These positive antenna gains and triple-bands of the proposed antenna are very attractive features for GSM/DCS/IMT-2000 bands handset applications.
