A Ultra-Wideband Two-Arm Self-Complementary Sinuous Antenna

InGaP/GaAs HBT MMIC Amplifier with Active Balun for Ultra-Wideband Self-Complementary Antenna

Novel Ultra-wideband Discone Antenna

A double-discone antenna for an ultra-wideband frequency scan is presented. An exquisite assembly of two inverse-feeding discone antennas shows a 30:1 broad bandwidth with VSWR below 2.5 and an omnidirectional radiation pattern. These features make the proposed antenna very suitable for both the UWB system antenna and the wideband scan antenna. © 2004 Wiley Periodicals, Inc. Microwave Opt Techn...

A Novel Ultra-Wideband Printed Monopole Antenna

In this paper, we introduce a novel printed monopole antenna for ultra-wideband (UWB) applications. The antenna is composed of two overlapped circular disc monopoles with a finite ground plane and fed by a 50 microstrip line. The designed antenna operates over impedance bandwidth (2.9 to 11.6GHz) for return loss S Ω 11 < -10dB. The antenna also shows omni-directional radiation patterns and good...

Design and compare of Two Coplanar Fed Ultra Wideband Antenna

In this paper, design and analysis of two compact coplanar waveguide (CPW) fed ultra wideband (UWB) slot antenna is presented. The proposed antenna consists of a rectangular slot on a ground plane and a triangular patch and another semi-circular patch at the interior portion of the feed that acts as tuning stub of the antenna. The return loss of the developed antenna are measured and compared, ...

A New Compact Ultra-wideband Linear Antenna Array for Target Detection Applications

This paper presents a low-cost compact planar microstrip-fed monopole antenna and its four-element array design for ultra-wideband (UWB) wireless communication and target detection applications, respectively, operating in the frequency span of 3 GHz to 11 GHz. A prototype was fabricated and then measured based on optimal parameters. The results of reflection coefficient (S11) and radiation patt...
