摘要

Power dividers with a good match over a wideband of frequencies are designed using Klopfenstein impedance taper for use with wideband antenna arrays. To validate the proposed design procedure a 2-way stripline, and a 2-way microstrip power divider are designed, fabricated, and measured. The measured return loss reveals better than -24 dB (from 4.3 GHz to 19.5 GHz) match for the 2-way stripline, and -27 dB (from 2.2 GHz to 12 GHz) match for the 2-way microstrip. Then a single Klopfenstein taper is used in the design of a 4-way stripline power divider. Measurements reveal return loss better than -22 dB (from 2.3 GHz to 19 GHz) for the 4-way stripline power divider. Furthermore, use of a single taper resulted in a shorter feed network compared to the traditional 4-way feed network using 2-way power dividers at two stages.
