Abstract
A short circuit protection system includes a first short circuit protection circuit, a second short circuit protection circuit and an antenna status detection circuit implemented only by hardware. The first short circuit protection circuit is configured to provide short-to-power protection between an antenna and a component. The second short circuit protection circuit is configured to provide short-to-ground protection between the antenna and the component. The antenna status detection circuit is configured to detect the operational status of the antenna.
