Abstract

Broadband monopole antennas have received
considerable attention owing to their attractive merits, such as
ultra-wide frequency band, good radiation properties, simple
structure and ease of fabrication. Since the Federal
Communications Committee (FCC) permitted the unlicensed use
of the ultra-wide band (UWB) frequency band in 2002, large
interests in both academic and industrial fields have been
attracted to research various UWB devices. Small UWB antennas
have found a wide range of applications including ground
penetrating radars, high data rate short range wireless local area
networks, communication systems for military, UWB short pulse
radars for automotive and robotics applications, C and X band
applications, and UWB microwave imaging systems. In this
paper, a novel compact planar UWB monopole antenna with
enhanced bandwidth by use of slots and Defected Ground
Structure (DGS) is presented. The size of the antenna is 50 mm x
50 mm and it has microstrip feedline. Design and analysis of the
antenna has been performed by HFSS software. Simulation
results show that the designed antenna has broad frequency band
which covers the band between 3.1 GHz and 10.6 GHz.
According the return loss results, this antenna can be used for
especially radar-based UWB systems applications which require
low to high frequencies.
