摘要

#CMT# #/CMT# The antenna has dielectric waveguides (2) whose parts are coupled via a boundary surface (5) that receives or radiates electromagnetic waves (1). The waveguide is made of a material with radar-transparent properties in a region of an electromagnetic field. A terminator (3) is arranged at an opposite end of a coupling surface and does not absorb residual energy from the waveguide. The terminator is made from a material with radar-transparent properties and formed with a radar-absorbing component at the end of the waveguide. #CMT# : #/CMT# The radar-absorbing component is fiber such as silicon carbide fiber and metal fiber. An independent claim is also included for a method for manufacturing a leaky wave antenna. #CMT#USE : #/CMT# Leaky wave antenna i.e. mechanically hinged antenna, for use in a radar system of a motor car for sensing environment. #CMT#ADVANTAGE : #/CMT# The integration of the terminator into the dielectric waveguide eliminates the absorption of residual energy caused by environmental conditions entering from the end of the waveguide, thus avoiding the temperature fluctuations, and hence improving properties of the antenna, and allowing the antenna to be independent of allowances caused by production. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a dielectric waveguide integrated with a terminator comprising a radar-absorbing component. 1 : Electromagnetic wave 2 : Dielectric waveguides 3 : Terminator 5 : Boundary surface #CMT#POLYMERS : #/CMT# The material for the dielectric waveguide is selected from plastic material such as polycarbonate and/or polyethylene.
