| Abstract | ||
| A new single layer, symmetrical microstrip fed compact circular patch with open-ended curve-shape slot ground is demonstrated and designed for Ultra-Wideband (UWB) applications. With the open-ended curve-shaped slot and circular patch fed by the micro-strip line, multiple resonant frequencies are excited and merged to form a measured widen operating bandwidth of 1.73 to 5.92 GHz with -10 dB return loss. Finite element simulations have been carried out to evaluate the performance of the modeled antenna using the HFSS v.11 electromagnetic (EM) simulator, from Ansoft. The proposed antenna is simulated with different ground slot width in order to study its effect on the bandwidth. In addition, the proposed slot antenna exhibits a small size of 30 × 30 mm. The simulated results show that, the proposed antenna has very good performance in impedance bandwidth with accepted radiation pattern, which makes it an excellent candidate in many ultra-wide band applications. The antenna is candidate to operate in Global System Mobile (GSM) and Wireless Local Area Communications (WLAN) 2.45 GHz and 5.8 GHz systems. | ||
