An adhesive (not shown) is interposed between each layer,
They were glued together using hot pressing to form a planar antenna. However, these planar antennas have the following
For example, a flexible film such as polyethylene terephthalate (100 μm thick) is used as the storage film 5; a low dielectric constant Teflon or polyethylene terephthalate (100 μm thick) is used as the dielectric layer 4;
2m, IIL, ) Aluminum plate (2+w+thickness) as the ground conductor 3; Aluminum foil (20pm thick) or @foil (35μm thick) as the microstrip line 2. In a planar antenna with such a configuration and materials used, the side conductor 3. 5, the substrate (dielectric material) 4 that is interposed between 5 and 5 inevitably generates loss from the power visiting body, which reduces the antenna gain margin against natural conditions such as rain, and causes noise and other effects on the image. , antenna configurations and materials that provide high gain are desired.
