System and method for integration of an antenna element and front-end module co-located into a speaker chamber

A base chassis assembly for an information handling system comprising:

• a metal top cover to house a speaker grill, the speaker grill covering a speaker to emit audio waves;
• the speaker grill formed within the metal top cover of the base chassis 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 metal top cover of the base chassis, where the peninsula serves as a speaker grill platform antenna;
• a cavity formed behind the peninsula, the cavity including walls formed around the back side of the peninsula to electrically isolate the cavity between the metal top cover and a metal bottom cover of the base chassis;
• and
• a printed circuit board assembly (PCBA) secured inside the cavity behind the peninsula of the speaker grill platform antenna including an antenna front end circuit operatively coupled to the speaker grill antenna to excite the speaker grill antenna via a contact pin coupling an excitation signal with the antenna front end circuitry.

An information handling system to transmit a communication signal comprising:

• a base chassis with a top metal cover and bottom metal cover, the top metal cover to house a speaker grill with a plurality of speaker grill apertures, the speaker grill covering a speaker to emit audio waves via the speaker grill apertures;
• the speaker grill formed within the metal top cover to form a speaker grill platform antenna to emit a target radio frequency (RF) when an excitation current is applied to a portion of the speaker grill, including:
• a slot formed around the portion of the speaker grill forming a peninsula on the speaker grill as the speaker grill platform antenna, where the slot physically separates the peninsula portion of the speaker grill from the metal top cover;
• a cavity formed behind the speaker grill with an electromagnetic isolation (EMI) wall placed around the perimeter of the cavity and the metal bottom cover of the base chassis forming the bottom of the cavity, where the cavity further serves as a speaker cavity;
• a printed circuit board assembly (PCBA) located within the cavity comprising:
• an antenna front end;
• a tuning module operatively coupled to the speaker grill platform antenna to, upon initiation of the antenna front end, excite the speaker grill platform antenna via a contact pin and dynamically switch frequencies based on the target frequency to be emitted by the speaker grill platform antenna;
• and
• a coaxial cable communicatively coupling the antenna front end to a processor.
