    Abstract: This study present a simple and slotted muti band rectangular microstrip patch antenna for wireless
communication system. A inverted U-shape slot and inverted L-shape notch has been loaded for design of the
rectangular microstrip antenna. Doing this the antenna is resonating with multi band frequency range and
fractional bandwidth of multi band proposed antenna is 6.09% (lower band), 23.11% (middle band) and 12.29%
(upper band) and antenna is resonating at 2.461, 3.938 and 5.579 GHz, respectively. The multi band frequency
of the proposed antenna design lie in the range of 1.97-2.24, 3.30-3.65 and 4.55-5.36 GHz, respectively. This
frequency band is suitable for wireless communication applications. The maximum gain of this designed
antenna has been enhanced up to 4.803 dBi and antenna efficiency is 99.87%. A microstrip line feed of 50 S has
been used in this proposed slotted microstrip antenna. The simulation process has been done by IE3D
simulation software tool.
