A compact slot antenna for UWB applications
A slot antenna configuration is proposed for UWB applications. The slot has a hybrid shape of the combination of a close ended circle and an open ended rectangle. The feeding structure of the slot is comprised of a 50 O microstrip connected to a circular patch and an open ended patch, forming an inverted L shape with circular corner. The antenna has a compact size of 21x26 mm2 printed on a 0.8 mm thick FR4. The measured 10dB bandwidth of the proposed antenna covers 3.03 11 GHz.
