Abstract :
A compact UWB planar antenna fed with a microstrip-line is proposed. The new design is composed of a square patch with a small size of 26 mm × 20 mm. with three rectangular slots and fed by 50 Ω microstrip transmission line and a reduced ground-plane which have a T-shaped slot. It is intended to be used in Microwave Imaging applications that cover the ultra-wideband (UWB) frequency band. A wider bandwidth of around 3.98 - 17.26GHZ with stable radiation pattern is achieved. The proposed antenna has excellent characteristics, low profile and cost-effective compared to existing UWB antennas. The UWB antenna is designed and analyzed using CST Microwave Studio and HFSS software in transient mode to verify antenna parameters improvements.
