Titel
A low-loss W-band frequency-scanning antenna for wideband multichannel radar applications
Abstract
A class of nonresonant slotted waveguide antennas particularly suited for wideband millimeter-wave radar and imaging applications is introduced. Inspired by a variation of the classic narrow-wall leaky structure, it possesses a high degree of design flexibility and is easily integrated into steerable arrays. A reliable manufacturing concept is presented and demonstrated by means of simulations and measurements on a first prototype, complemented by an experimental evaluation of the antenna's in-system performance as part of a frequency-modulated continuous-wave radar.
