A dual band multi-pitch helical antenna (101) includes a first section (201) positioned adjacent to the feed point having a widely spaced pitch. A second section (203) is attached to the first section (201) having a narrowly spaced pitch. A third section (205) is attached to the second section (203) having a widely spaced pitch, while a fourth section (207) is attached to the third section (205) having a narrowly spaced pitch. The antenna further includes a parasitic element (213a/213b) that is positioned adjacent to each of the first section (201), second section (203), third section (205), and fourth section (207) for enhancing broad-band antenna performance. A matching network (216) is connected between an antenna feed point and the first section (201) for matching the dual band multi-pitch helical antenna to a predetermined feed point impedance such that the antenna is resonant in at least two frequency bands.
