This paper presents novel dual tapered helical antenna structures that are 3D printed and nested within each other for size reduction. Each tapered helical antenna element is designed to operate at a distinct span of frequencies. The two helical antennas are nested together and wrapped in opposite direction to each other in order to satisfy orthogonal polarization. The two helical elements are fabricated using a laser based 3-D printing process where good measured radiation behavior is obtained.
