60 GHz foam-based antenna for near-field focusing

An innovative way to manufacture a sectoral horn antenna with a biconvex dielectric lens is presented. The antenna focuses on the near-field signal in the H-plane to illuminate a linear array for example. It is made of only two symmetrical pieces of foam and a metallic support. A prototype is manufa...

Zusammenfassung:	An innovative way to manufacture a sectoral horn antenna with a biconvex dielectric lens is presented. The antenna focuses on the near-field signal in the H-plane to illuminate a linear array for example. It is made of only two symmetrical pieces of foam and a metallic support. A prototype is manufactured and measured at 60 GHz to verify its focusing properties and validate the technological process.
