3-D-Printed Spiral Leaky Wave Antenna With Circular Polarization

Abstract: This article presents the design, manufacturing and measurement of a fully dielectric leaky wave antenna operating at 18 GHz. The antenna is composed of a grounded dielectric substrate with a top dielectric Archimedean spiral corrugation, which allows obtaining a directive pencil-beam in broadside direction with circular polarization depending on the turning sense of the spiral. The 3D-printing implementation allows having two new degrees of freedom for the spiral when compared to other previous implementation… Show more

“…This is obtained in 3-D, by regulating the material infill percentage and the empty/full pattern ratio. In this way the designer takes advantage of an almost unlimited number of degrees of freedom in the material synthesis, even in the microwave/millimeter-wave range for both circuit [4] and antenna [5] applications. 3-D printing is particularly suitable to meet the internet of things (IoT) requirements in terms of miniaturized, low-cost electronic technologies for healthcare applications, where wearable, lightweight, non-invasive systems need to be adapted to curvilinear surfaces of the body [6].…”
