Abstract
AbstractA hemispherical‐shaped folded electrically small antenna (ESA) is a well‐known antenna where the radiating conductor is a wire or flat strip of variable width. This work analyzed the performance of strip‐based ESA for a constant strip width and focused on the fabrication procedure which utilizes the low‐cost dielectric material and ubiquitous 3‐D printer. The impact of additional dielectric support on the performance of ESA was investigated. This work also introduced conductive paint for the radiating part, along with metallic wire and strip. There is a good agreement between simulated and measured results. The 3‐D printing technique offers design flexibility, eases fabrication difficulty, reduces material cost, and improves the mechanical stability of the antenna.
