Abstract

A wireless electronic device includes first and second conductive layers arranged in a face-to-face relationship. The first and second conductive layers are separated from one another by a first dielectric layer. The wireless electronic device includes a first radiating element and a second radiating element. The first conductive layer includes a slot. The second conductive layer includes a stripline. The second radiating element at least partially overlaps the slot. The wireless electronic device is configured to resonate at a resonant frequency corresponding to the first radiating element and/or the second radiating element when excited by a signal transmitted and/or received though the stripline.
