Abstract	In this paper we present a new UWB antenna and its linear phased array. The single UWB element has omnidirectional and stable radiation patterns over a wide-bandwidth that make it suitable for UWB wireless communication. In addition an E-plane phased array design of four proposed UWB antennas has been simulated to achieve beam steering capability which is used in high accuracy phased array radar. Phase of each element applied by the well-known progressive phase shift method. The proposed phased array antenna has a wide beam steering capability of ±30° and an average of -10 dB side lobe level (SLL) in over a wide bandwidth from 3 to 11 GHz. The simulated and measured results of return loss for the single antenna, both single and array Gain, and beam scanning feature will be discussed. The simulation results confirm that the proposed UWB phased array has a stable radiation pattern and perfect cross polar isolation in the entire band of operation for mentioned beam scanning angles.
