1. A multi-layer laminate antenna comprising:

  • a feed line configured to convey electricity;

    a radiator coupled to the feed line, comprising metal disposed in a first layer of the antenna, and having an edge of a length to radiate energy at a radiating frequency; and

    dummy metal disposed in a second layer of the antenna that is different from the first layer of the antenna, the dummy metal configured to radiate an insignificant amount of energy, if any, at the radiating frequency;

    wherein a first portion of the dummy metal is at least partially disposed outside an overlapped area of the second layer that is overlapped by the radiator and is configured such that any linear edge of the first portion of the dummy metal disposed outside the overlapped area is less than half of a radiating wavelength corresponding to the radiating frequency, andwherein the dummy metal is absent from a region of the second layer that overlaps a perimeter of the radiator, the dummy metal being displaced from a first orthogonal projection of a perimeter of the radiator onto the second layer.
