Microstrip antenna

Abstract

Abstract PURPOSE:To obtain a microstrip antenna which can be used outdoors for a long period of time with excellent weather resistance and electrical characteristics, by forming previously a radiation element and a microstrip line on a dielectric film, etc. and then laminating them on a dielectric substrate. CONSTITUTION:A radiation element 7 and a microstrip line 10 are formed on a dielectric film or a dielectric plate 13. This plate 13 is adhered to a dielectric substrate 8 so that the side where the element 7 and line 10 are formed touches the substrate 8. Finally a feed terminal 11 is connected to the line 10 to obtain a microstrip antenna. In such a constitution of this antenna, both the element 7 and the line 10 are completely covered with a dielectric substance in an airtight structure and never exposed to the open air. Thus, the corrosion due to oxidation, etc. is eliminated and the weather resistance of the antenna is improved.
