| Popis: |
A novel kind of miniaturized wideband patch antenna is designed and analyzed. The antenna is having size of 2.1cm × 2.1cm × 1.25cm and patch is having area of 153mm2. Single or dual band frequency response can be obtained by varying the feed location, height of the substrate and the geometric specifications of the antenna. This proposed antenna can be used for GSM 1800, GSM 1900, UMTS, Wi-Max and UWB applications. Bandwidths up to more than 56% can be obtained. At each band, obtained corresponding VSWR is near to 1. The proposed antenna provides good return loss S11 and impedance behavior. Far-field radiation pattern and field distributions on the coaxial probe feed patch have been analyzed. |
