Abstract
A transmission line structure includes a routing trace, a doped region and a first guard trace. The routing trace is disposed over a substrate. The doped region is disposed in the substrate and the projection of at least the partial routing trace falls within the doped region. The first guard trace is located over the substrate and disposed with a space from the routing trace, wherein the first guard trace is grounded and electrically coupled with the doped region. In addition, the conductivity of the first guard trace is higher than the conductivity of the doped region.
