Abstract: Mobile and wireless communication technologies are rapidly growing industrial markets since the last two decades. The future of these communication systems is to provide high data rate at anytime, anywhere in the world. In order to transmit and receive more and fast information, large bandwidth is required. To achieve this, we require antennas with property of wide bandwidth or multi bandwidth. Therefore, bandwidth enhancement is currently a popular topic of research. This is achieved by the introduction of UWB range by FCC for the specific bandwidth of 7.5 GHz (i.e., from 3.1-10.6 GHz). It is planar, cheap, and compact in size and have low profile with the VSWR ≤ 2 across the whole band of operation. The focus of this paper is to study and analyse the types of UWB antennas, which are available and previously designed. Along with that different method of notching frequency bandwidths, for filtering purpose are studied.
