Abstract
An electronic device and associated methods are disclosed. In one example, the electronic device can include an assembly having asymmetrically situated conductors. In selected examples, the assembly includes a ground plane, a central shield portion, a first side shield portion on a first side, a second side shield portion on a second side, a first conductor asymmetrically situated between the central shield portion and the first side shield portion, a second conductor asymmetrically situated between the central shield portion and the second side shield portion, and dielectric within the assembly.
