Abstract

A novel compact microstrip-fed slot antenna design is proposed. By properly loading a notch to the open-ended T-shaped slot and extending a small section to the microstrip feed line, multiple resonant frequencies are excited and merged to form a large enough 10-dB return loss bandwidth (measured from 3.1 to 11.45 GHz) for ultrawideband (UWB) applications. The vital parameters of the proposed antenna are illustrated, and a prototype is constructed and experimentally studied. The measured results show good radiation patterns and stable signal transmission within the band of interest.
