Patent ID: 7795653

Claim:
An electronic device, comprising: a first radiation region; a second radiation region spaced apart from the first radiation region; an insulating region having a first side and a second side opposite the first side, wherein: the first radiation region lies immediately adjacent to the first side; the second radiation region lies immediately adjacent to the second side; within the insulating region, no other radiation region lies between the first and second radiation regions; and the insulating region includes an insulating layer that includes a plurality of openings; and a first spectral layer including a first portion and a second portion, wherein: the first portion of the first spectral layer lies within the first radiation region; the second portion of the first spectral layer lies within a first opening of the insulating layer, wherein the plurality of openings includes the first opening; and from a plan view, the first spectral layer overlies only a portion of the insulating layer within the insulating region.
