Some embodiments relate to a semiconductor module comprising an integrated antenna structure configured to wirelessly transmit signals. The integrated antenna structure has a lower metal layer and an upper metal layer. The lower metal layer is disposed on a lower die and is connected to a ground terminal. The upper metal layer is disposed on an upper die and is connected to a signal generator configured to generate a signal to be wirelessly transmitted. The upper die is stacked on the lower die and is connected to the lower die by way of an adhesion layer having one or more micro-bumps. By connecting the lower and upper die together by way of the adhesion layer, the lower and upper metal layers are separated from each other by a large spacing that provides for a good performance of the integrated antenna structure.
