Patent ID: 7728779

Claim:
An electronic device comprising: a unitary circuit board; a radio-frequency (RF) antenna attached to the circuit board and including a radiating plane and a ground plane, wherein a feed line on the circuit board is connected to the radiating plane and a ground line on the circuit board is connected to the ground plane; and a microphone attached to the circuit board and spaced apart from the RF antenna by a distance of less than a half wavelength of a resonant frequency of the radiating plane, wherein the microphone is configured to generate a microphone signal through a pair of microphone lines on the circuit board, wherein the radiating plane comprises a planar F radiating plane; and wherein the pair of microphone lines extend away from the RF antenna along a major length thereof in a direction perpendicular to a direction of major resonant current flow in the planar F radiating plane while transmitting to reduce electrical interference from the radiating plane that is combined with the microphone signal on the microphone lines.
