Abstract:
An information handling system to wirelessly transmit and receive data may include a base chassis including a metal C-cover and metal D-cover to house a processor, a memory, and a wireless adapter, the metal C-cover to house a speaker grill, the speaker grill covering a speaker to emit audio waves; the speaker grill formed within the C-cover to emit a target radio frequency (RF) including a slot formed around a portion of the speaker grill forming a peninsula on the speaker grill that is physically separated from the C-cover; an antenna element placed behind the speaker grill and operatively coupled to the wireless adapter; an electromagnetic interference (EMI) shield forming a cavity enclosing the speaker and the antenna element, including a plurality of metallic shielding walls extending from the C-cover to a D-cover of the information handling system; and a conductive rubber gasket placed between the plurality of conductive walls and the D-cover to shield the cavity from EMI sources.
