A Wide-Band Printed Circuit Dipole

Abstract

A printed circuit dipole with integrated balun is presented that has achieved measured bandwidths of 40 percent over a 2:1 VSWR range. The microstrip balun features a double-tuning capability that provides the diploe with an impedance match over a wide band of frequencies. Simple transmission line theory is used to analyze the balun structure, whereas the method-of-moments is utilized to determine the dipole current distribution. Two dipoles were fabricated and tested in order to validate the dipole/balun design equations. Antenna patterns are taken at several frequencies over the operating band to determine any frequency dependence of the patterns. VSWR measurements and cross- polarization patterns are also presented.
