Definitions

  • the antenna element 10c is different from the antenna element 10 in that it is provided with the signal conductor layer 60 instead of the signal electrode 22 and is not provided with the interlayer connection conductors v53 and v54.
  • the direction from the first radiating conductor layer 20 toward the upper end ground conductor layer 160 is defined as the first direction.
  • the first direction is the right direction.
  • the direction orthogonal to the first direction when viewed in the vertical direction is defined as the second direction.
  • the second direction is the front-back direction.
  • the length of the upper end ground conductor layer 160 in the second direction is longer than the length of the first radiating conductor layer 20 in the second direction.
  • the length of the upper end ground conductor layer 160 in the front-rear direction is longer than the length of the first radiation conductor layer 20 in the front-rear direction.
  • the upper end ground conductor layer 160 may be arranged in only one direction when viewed in the vertical direction from the first radiating conductor layer 20.
  • the antenna element 10e is different from the antenna element 10d in that the second ground conductor 216 is further provided.
  • the second ground conductor 216 is provided on the insulating base material 12. More specifically, the first ground conductor 16 and the second ground conductor 216 are located in different directions from the first radiation conductor layer 20 when viewed in the vertical direction. More specifically, the first ground conductor 16 is located to the right of the first radiation conductor layer 20 when viewed in the vertical direction. The second ground conductor 216 is located behind the first radiation conductor layer 20 when viewed in the vertical direction.
  • the upper end ground conductor layer 260 which is the upper end of the second ground conductor 216, is provided on the upper main surface of the insulator layer 14a.
  • the first radiation conductor layer 20 is provided on the upper main surface of the insulator layer 14b. Therefore, the upper end of the second ground conductor 216 (the upper main surface of the upper end ground conductor layer 260) is located above the first radiation conductor layer 20.
  • the upper end of the upper end ground conductor layer 160 may be positioned above the first radiation conductor layer 20 by utilizing the deformation of the insulating base material 12.
