Abstract: An input signal is transmitted to a component. A distortion associated with the component is determined based, at least in part, on an output signal generated by the component in response to the input signal. A distortion error measurement associated with the component is determined based, at least in part, on the distortion and the output signal generated by the component. A memory effect and the associated nonlinearity within the component are quantified based, at least in part, on the distortion error measurement.

Abstract: An embodiment of the present invention is a modified inverted-F antenna for wireless communication. The antenna circuit includes a dielectric substrate having a first surface, a radiating stub on the first surface of the dielectric substrate, and a first ground plate on the first surface of the dielectric substrate to couple to ground. The first ground plate includes one or more grounded capacitive stubs spaced apart from the radiating stub. The one or more grounded capacitive stubs tune performance parameters for the antenna circuit.
