W-band high gain lens antenna for metrology and radar applications

A W-band high gain lens antenna has been realised and measured. A hyperbolic lens made in an ECCOSTOCK 0005 is associated to an optimised modified circular horn related to a circular-to-rectangular waveguide transition in order to fit the WR-10 standard waveguide. The antenna provides more than 30 d...

Zusammenfassung:A W-band high gain lens antenna has been realised and measured. A hyperbolic lens made in an ECCOSTOCK 0005 is associated to an optimised modified circular horn related to a circular-to-rectangular waveguide transition in order to fit the WR-10 standard waveguide. The antenna provides more than 30 dBi gain between 75 GHz and 110 GHz. It is competitive in several fields of applications: first, obstacle detection radar application (at 77 GHz or 94 GHz), secondly metrology, for example, to measure radar cross-sections over the whole W-band with a single antenna.
