摘要： An electromagnetic device includes: a substrate comprising an elongated aperture having an overall length, L, and an overall width, W, as observed in a plan view of the device, where L is greater than W; a dielectric medium comprising a dielectric material other than air disposed on the substrate substantially covering the aperture, the dielectric medium having a cross sectional boundary, as viewed in the plan view of the device, that is symmetrical with respect to an in-plane axis of reflection of the dielectric medium; wherein the device is configured such that a line perpendicular to the overall length L of the elongated aperture and passing through a center point of the elongated aperture is not any in-plane axis of reflection.

摘要： An antenna includes a substrate and an electromagnetic, EM, radiator. The substrate includes a magnetodielectric material. The EM radiator includes an electrically conductive material disposed on an upper surface of the substrate. The EM radiator further includes a root, and a pair of forks that are contiguous with and extend from the root along a first axis. The pair of forks are separated from one another by a slot in the electrically conductive material of the EM radiator to define a fork-shaped EM radiator. The root includes a bridge portion extending between the pair of forks in a direction of a second axis perpendicular to the first axis to electrically connect together the pair of forks.
