Broadband conical printed quadrifilar helical antenna with integrated feed network

Abstract

Abstract A new approach to designing a broadband printed quadrifilar helical antenna (PQHA) is presented. The printed wire is conical in shape, while the feed network is directly integrated underneath the antenna. The entire system is designed using Ansoft HFSS. Good agreement with the experimental results is obtained. The impedance and axial ratio bandwidth values are greater than 32.4% and 18.5%, respectively. © 2002 Wiley Periodicals, Inc.
