Patent abstract
Electronic devices and wireless communication terminals include a unitary circuit board on which a radio-frequency (RF) antenna and a microphone are attached. The RF antenna includes a radiating plane and a ground plane. 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. The microphone and the RF antenna are spaced apart on the circuit board by a distance of less than a half wavelength of a resonant frequency of the radiating plane. The microphone generates a microphone signal through a pair of microphone lines on the circuit board.
