Abstract
A liquid level sensor system can include a container configured to hold a volume of a liquid and a monopole antenna arranged proximate the volume of the liquid. A radiofrequency circuit may be configured to apply a radio frequency signal to the monopole antenna and provide one or more signals indicative of a level of the volume of the liquid within the container based on a radio frequency characteristic of the monopole antenna.
