Abstract:

A printed circuit dipole with integrated balun is presented that has achieved measured bandwidths of 40 percent over a 21 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 dipolebalun 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.
