Abstract A printed apollonian gasket monopole antenna with CPW‐feed is proposed for ultra‐wideband applications.The Ultra‐wide bandwidth of this antenna is achieved by modified the CPW ground plane. The experimental result of this antenna exhibits the ultra‐wideband characteristics from 2.8 to 15 GHz at VSWR 2:1. The simulated results calculated from high frequency structure simulator are in good agreement with experimental results. The measured radiation patterns of this antenna are omnidirectional in H‐plane and bidirectional in E‐plane. The radar cross section (RCS) of this antenna is also studied for structural mode and antenna mode scattering. This type of antenna can be useful for a number of applications such as ultrawideband system, radar, ground penetrating radar, medical imaging, and other military applications. © 2012 Wiley Periodicals, Inc.
