Federal Communications Commission (FCC) has allotted a bandwidth of 7.5GHz (from 3.1GHz to 10.6GHz) for ultra wideband (UWB) wireless communications, UWB is rapidly advancing as a high data rate wireless communication technology. In this paper requirements for the Ultra-wideband antennas for wireless system are discussed UWB applications are becoming very popular because of reliability, security and high speed data transmission over smaller distances. In these applications it is very much essential to have small size printed antennas for transmitting and receiving of UWB signals. The research into UWB transient antennas has also made significant contributions to the development and improvement of wideband continuous wave (CW) antenna designs. However, designing small size printed antennas with good performance is quite a challenging task.This paper gives a state of art on covering the areas of UWB fundamentals, antenna theory, and it focuses on UWB planar printed circuit board (PCB) antenna design and analysis. It also presents a summary of key UWB antenna concepts, as well as system and network considerations, and fundamental limits for UWB antennas. These antennas can be used in many applications like 4G, wireless body area networks, spectrum sensing in cognitive radio, wireless telemetry, telemedicine and RF energy harvesting. GPR, MIMO, wireless personal networks, wireless sensor networks and so on.
