AB  - The rapid development in wireless technology has necessitatedcompact devices and these compact
devices required miniature antennas for different applications. Many researchers carried out work to reduce size
of antenna. There are different methods proposed by different researchers to reduce the size of the antenna
without effecting the gain and bandwidth .The techniques used in the literature are using dielectric substrates
with high permittivity, applying magneto inductive wave guide loading or using slots and notches on the patch
of the antenna, embedding fractal slots but the simple method to reduce the size of the antenna is using
Defective Ground Structure (DGS). In this study, two different Ultra Wide Band (UWB) monopole antennas
are designed and their performance is compared by placing bevel slots on patch and without placing the bevel
slots. Both the UWB Monopole antennas are operating in the frequency band of 2.4-12 GHz with band notching
from (5.1-5.9 GHz) is designed. Performance evaluation of this antenna is carried out using HFSS software. The
results are presented and discussed. The designed antenna with bevel slots on patch is fabricated and tested
for return losses and VSWR and the results are compared.
