Claim Text:
1. A mobile computing device comprising: a speaker trace etched on a portion of a printed circuit board (PCB) of the mobile computing device, at least a portion of the speaker trace comprising a speaker contact; a speaker coupled to the speaker contact, the speaker configured to receive an audio signal; an antenna wherein at least a portion of the antenna is disposed on top of at least a portion of the speaker and wherein the antenna is configured to tune, by using the speaker trace, to an operating frequency for receiving a radio frequency (RF) signal during substantially a same time as the audio signal is received by the speaker, the operating frequency being greater than a frequency of the audible signal, the speaker trace being a part of the antenna; an inductor coupled to a portion of the speaker trace that receives the RF signal and adjacent to a portion of a ground trace, the inductor configured to operate as an open circuit that isolates the antenna from the ground trace, the inductor having a high reactance value that impedes current at the operating frequency; an electrostatic discharge (ESD) protection diode connected in series with the inductor, the ESD protection diode being coupled to a first ground included on a first portion of the ground trace and coupled to a first portion of a second speaker trace; and a capacitor connected in parallel with the ESD protection diode, the capacitor being coupled to a second ground included on a second portion of the ground trace and coupled to a second portion of the second speaker trace, the inductor configured to prevent the antenna from being electrically coupled to the first ground and the second ground at the operating frequency.
