Abstract :
A dual-band tapered slot omni-directional antenna with an orthogonal arc-shaped parasitic element which covers GSM/DCS/PCS/CDMA2000/WCDMA/TD-SCDMA/WLAN/ WiMAX is realized experimentally. The proposed antenna consists of two shunted tapered slot antennas. The tapered slot antenna is an asymmetric structure which is made up of a straight line and an exponential line. An arc-shaped parasitic element which improves the radiation pattern effectively is orthogonal with the radiator element. The measured 14-dB impedance bandwidth of the antenna is 29.5% and 54.6% at the lower band and the higher band, respectively. And the measured 10-dB impedance bandwidth is 129.2% (0.69GHz-3.21GHz) centred at 1.95GHz, which is about 45 times that of the corresponding monopolar wire-patch antenna. The proposed antenna is successfully simulated, designed, and measured, showing dual-band impedance bandwidth, stable gain and good omni-directional radiation patterns.
