Abstract

A slot array antenna for a vehicle radar system is provided. The antenna includes a cavity which separates a magnetic field signal applied through a feeding waveguide while maintaining phase and amplitude and which radiates such signals to the each radiating slot. A slot array antenna includes a 2-by-2 unit cell arrangement and a feeding plate member that forms a feeding waveguide. In addition, a first slot plate member includes a coupling slot, a cavity plate member forms a cavity, and a second slot plate member has a plurality of sequentially laminated radiation slots. Further, the cavity includes a partition wall for impedance matching.

Description

[0001] Cross References to Related Applications [0002] Pursuant to 35 U.S.C. §119(a), this application claims the benefit of Korean Application No. 10-2014-0098402 filed July 31, 2014, the entire contents of which are incorporated herein. technical field [0003] The present invention relates to a slot array antenna for a vehicular radar system, and more particularly, to a slot array antenna for a vehicular radar system comprising a layered structure, due to the repeated structure of a plurality of unit cells, the The slot array antenna has increased design freedom and is also ultra-thin, lightweight, has low-loss characteristics, and also has broadband characteristics due to the broadband feed structure. Background technique [0004] Vehicle radar systems are generally mounted on the front of the vehicle, and are required to be thin and lightweight. Since higher frequency signals (eg, signals exceeding tens of GHz) are usually transmitted and received at constant field s...
