Description

[Brief explanation of the drawing]

FIG. 1 is a perspective view showing a microstrip array antenna according to an embodiment of this invention, and FIG. 2 is a perspective view showing an embodiment of a conventional antenna of this type. In the figure, 1 is a dielectric skin, 2 is a radiating element, 3 is a feeder line, 4 is a dielectric core, 5 is a ground conductor, 6 and 7 are upper and lower pipe wall conductors, 8 and 9 are left and right pipe wall conductors, and 10 is a In the support rod, 11 is a center conductor, and 12 is a coaxial tube. In addition, in the figures, the same reference numerals indicate the same or corresponding parts.

Claims (1)

[Claims for Utility Model Registration] (1) Metal foil of any shape is formed on a dielectric skin coated on one side of a dielectric core to form a radiating element, and the other side of the dielectric core is coated with a metal foil of an arbitrary shape. 1. A microstrip array antenna having a sandwiched trench structure in which a conductive skin is applied to a surface of a coaxial tube to form a ground conductor, characterized in that the ground conductor is also used as a part of the outer conductor of a coaxial tube. (2) The microstrip array antenna according to claim (1) of the utility model registration, characterized in that the ground conductor is made of carbon fiber reinforced plastics. (3) Utility model registration claim No. (1), characterized in that the outer conductor of the coaxial pipe has an open cross section other than the part that is used as the ground conductor, and is combined with the ground conductor to form a closed cross section outer conductor. The microstrip array antenna described in (2). (4) The microstrip array antenna according to claim (3) of the utility model registration, characterized in that part or all of unnecessary parts of the outer conductor of the coaxial tube are removed.
