Zusammenfassung:	The correlated energy gain (CEG) is introduced to describe the time‐domain characteristics of the UWB antenna for pulse radio systems. To improve the time‐domain performance of the pulse UWB system, a planar goblet‐like UWB antenna is proposed. The dimensions of the antenna are optimized using the mean effective CEG (MCEG) as the cost function. Because the MCEG considers the radiating energy and the pulse shape preserving capability simultaneously, the designed antenna can achieve good time‐domain characteristics. The designed antenna is fabricated and measured in time‐domain. Good pulse shape fidelity is observed. © 2010 Wiley Periodicals, Inc.
