Abstract

A state‐of‐the‐art multi‐octave band‐printed circuit log‐periodic antenna (LPA), which can characterize signal polarization accurately, has been designed and developed. A broadband compact‐size cylindrical cavity has been developed for the LPA. The feeding mechanism for the cavity‐backed structure was implemented using a Chebyshev‐tapered printed circuit balun. The antenna can be flush‐mounted with the platform surface and hence finds wide application in electronic warfare (EW) systems. The technique involved in the development of this antenna and its feeding mechanism along with the measurement results are presented. © 2002 Wiley Periodicals, Inc.

## Abstract 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

## Abstract This article presents the design of a novel ultra‐wideband microstrip‐fed planar monopole antenna with dual band‐notched characteristics. The proposed antenna achieved an impedance bandwidth of 3.1–11.7 GHz with VSWR <2, except the bandwidths of 3.3–4.0 GHz for WiMAX and 5.5–6.3 GHz for

## Abstract Many research works have emerged for ultra‐wideband (UWB) systems. One important issue is the antenna design to cover all frequency bands (3.1–10.6 GHz). In most applications, a reduced compact antenna is needed but with several requirements. In this paper, a novel triangle–semicircular
