Abstract: For the exchange of high rate information, wide band antennas are needed and their usage increased tremendously now a days. One of the major challenges in the design of wideband antenna is the design of a small size antenna while providing wide bandwidth, omni-directional radiation pattern and stable gain. The proposed antenna consists of a monopole antenna with polygon shaped patch. Fractal elements are added to the polygon patch and defected ground structure is experimented for the enhancement of bandwidth. The size of the proposed antenna is 25×25×1.6 mm3 and is prototyped on FR4 substrate whose permittivity is 4.4. The proposed antenna should provide wideband and it is useful for wireless communication applications.
