Abstract
An antenna module with antenna signal indicating function includes a substrate unit, an antenna unit and a light-emitting unit. The antenna unit has an antenna trace fanned on the substrate unit, and the antenna trace has an antenna body having a grounding portion electrically connect with the antenna body and a feeding portion electrically connect with the antenna body for simultaneously receiving RF signals and DC. The light-emitting unit has a light-emitting element electrically connected between the antenna body and the feeding portion, thus the antenna body and the light-emitting element share the grounding portion. When the user turns on the antenna function of the laptop to receive RF signals, the antenna unit and the light-emitting unit can respectively receive RF signals and DC. Hence, users or bystander could easily judge whether the antenna unit is in use according to light or dark of the light-emitting unit.
