摘要：<p>A helical antenna having a simple structure and being made of cheap conductor to reduce the manufacturing cost, and a manufacturing method thereof. A helical antenna comprises a dielectric core, a conductive strip, a feeding conductor, and an external circuit. The dielectric core has a substantially cylindrical shape with an outer circumferential surface on which a spiral groove is formed. The conductive strip is deposited on the groove of the dielectric core. The feeding conductor is placed under the dielectric core and provides an electrical connection between the conductive strip and an external circuit. The antenna cover encloses the dielectric core and the feeding conductor. <IMAGE> <IMAGE></p>
