Abstract

In this paper, a low-profile miniaturized microstrip monopole antenna with an overall size of 15 mm×20 mm×1.6 mm is developed and analyzed for Ultra-Wide Band (UWB) services. The proposed antenna is carefully designed, optimized, and analyzed using HFSS 15 simulation software. A prototype of the design is realized and experimentally tested as proof of concept. The results are discussed and compared with literature. They show attractive radiating features for UWB applications. The proposed antenna consists of an elliptical patch printed on a low-cost FR-4 epoxy substrate with a modified ground plane. To achieve UWB characteristics, elliptical rings are etched on the conducting patch, and the ground plane is modified by adding an inverted L shaped strip and creating a semi-elliptical slot in the partial ground opposite to the feed line. The achieved ultra-wide band ranges from 3.1 to 18.1 GHz (141.51%).
