Abstract

This paper presents a low‐profile broadband design of a printed quadrifilar helical antenna for the application as a broadcasting satellite receiving antenna in the frequency range of about 2.3 to 2.7 GHz. The antenna comprises four parallel printed strips excited in phase quadrature and rolled into a helical shape on a foam cylinder of diameter 22 mm and height 27.2 mm. The antenna shows broadband circular polarization (CP) operation with a 3‐dB axial‐ratio bandwidth of about 670 MHz or 27.9% centered at about 2.4 GHz. Good antenna gain is also obtained. © 2002 Wiley Periodicals, Inc. Microwave Opt Technol Lett 36: 134–136, 2003; Published online in Wiley InterScience (www.interscience.wiley.com).

## Abstract A very‐low‐profile (VLP) broadband planar antenna is developed for DCS‐1800 and IMT‐2000 handsets. The VLP planar antenna consists of an S‐strip and a T‐strip, which are separately printed on the two sides of a thin substrate. The antenna height is only 4.8 mm which is much lower than p
