Abstract
A quadrifilar helical antenna includes a conical supporting medium, a feed network, and four sets of antenna composite elements. Each set of antenna composite element includes at least one short-circuit helical arm and at least one open-circuit helical arm. The short-circuit helical arm and the open-circuit helical arm in each set of antenna composite element are sequentially wound on an outer wall of the conical supporting medium in one winding direction. In an axial direction of the conical supporting medium, a projection length of the short-circuit helical arm is greater than that of the open-circuit helical arm in each set of antenna composite element. The four sets of antenna composite elements are respectively coupled to a feeding point of the feed network for feeding, and the short-circuit helical arms in the four sets of antenna composite elements are in short-circuit connection. The antenna provided by embodiments of the present disclosure can efficiently improve the gain and gain bandwidth of the antenna under the condition that total occupation space is limited.
