Popis: This article firstly introduces a compact printed patch antenna with ultrawide bandwidth. The performance is achieved by placing the radiating patch above a rectangular notch cut in the finite ground plane edge. This fabrication provides an ultrawide impedance bandwidth and reduced antenna dimension by suitable separations of the patch from the notch edges. A practical design and experimental results for the requirement of WiMax 802.16e are presented. Moreover, using the proposed antenna as the complementary elements, a dual-polarization ultrawideband antenna design is implemented and studied. The experimental results indicate that not only the original characteristics are preserved from the dual-polarized integration but also a larger than 25-dB isolation is achieved throughout the operating band. In addition, omni-directional radiations in the azimuthal plane are achieved to make the proposed dual-polarization antenna more suitable for mobile communications. © 2009 Wiley Periodicals, Inc.
