Abstract
A biostimulator, such as a leadless cardiac pacemaker, having a patch antenna integrated into a housing, is described. The housing includes an annular wall that contains electronic circuitry of the biostimulator and provides a ground plane of the antenna. The patch antenna includes a meandering trace embedded in a curved dielectric layer that is mounted on the annular wall. The trace provides a conductor of the antenna and the dielectric layer provides a dielectric substrate of the antenna between the conductor and the ground plane. The electronic circuitry contained within the annular wall is electrically connected to the trace via an electrical feedthrough that passes through the annular wall and the dielectric layer. The electrical feedthrough places the electronic circuitry in communication with the antenna to transmit or receive wireless communication signals from an external device. Other embodiments are also described and claimed.
