## Abstract A novel dual band‐notched monopole ultra‐wideband antenna is proposed, in which the parasitic strip creates one band‐notch at 5.5 GHz and the tuning stub produces another band‐notch at 3.5 GHz. The experimental results show that the proposed antenna, with a compact size of 20 __×__ 31.5

Abstract
In this study, a systematic and simplified design procedure for quasi‐Yagi antennas is presented. The design is based on the simple field and impedance matching among antenna components. This new antenna design is possible due to the newly developed ultra‐wideband balun. Two types of wideband quasi‐Yagi antennas are successfully designed and implemented in Ku‐ and Ka‐band with frequency bandwidths of 53.2% and 29.1%, respectively. © 2008 Wiley Periodicals, Inc.

## Abstract A mixed model of two‐dimensional (2‐D) genetic algorithm and finite‐difference time‐domain is applied to the automatic design of ultra wideband (UWB) planar antennas in a finite size. The results illustrate that the method is valid and a new UWB antenna is designed successfully in the s
## Abstract An ultra‐wideband antenna is designed using genetic optimization and the finite‐difference‐time‐domain (FDTD) method. Efficiency is enhanced by using the Green's function method (GFM) as an absorbing boundary condition (ABC) close to the antenna surface, and as a propagator to the radia
