System Design Considerations of a Generic Integrated Frequency‐Modulation Continuous‐Wave Radar Front‐End

Abstract

Integrated frequency‐modulation continuous‐wave radars are attractive to a wide range of industrial and commercial applications. The design considerations unique to such an integrated radar front end are studied in this work. Theoretical models as well as experiment results are presented, which verify the effectiveness of the proposed design approach. © 2013 Wiley Periodicals, Inc.

Performance comparison between a surface‐volume hybrid integrated mixer and a surface integrated mixer

“…Experiment results show that this so-called surface-volume hybrid integration approach demonstrates advantages when compared with a monotonous integration approach under certain circumstances. Previously, the design and implementation of a frequencymodulation continuous-wave radar front-end system-on-substrate have been reported [1,2]. To design such an integrated frontend, the transition between a "surface" transmission line, that is, the microstrip, and a "volume" transmission line, that is, the substrate integrated waveguide (SIW) is required [3].…”

“…Graphene is a material formed by carbon atoms arranged in a flat two-dimensional (2D) hexagonal structure that possesses excellent mechanical, electrical, and optical properties [1]. Many researches for application of graphene as ultrahigh-speed transistors [2], transparent solar cells [3], metamaterials [4], and graphene plasmonics [5,6] are currently in progress.…”

Optimization of a novel substrate integrated waveguide high-pass filter using space mapping

“…Conversely, the SIW filter is to achieve the performance of traditional metallic waveguide filter on the substrate, and has the advantages of small volume, light weight, low cost, easy fabrication, and easy integration with other planar structure. Conventional metallic waveguide filters do not have these advantages . Based on the above advantages, SIW filter has been widely studied.…”
