ABSTRACT:
The present disclosure includes a system and method for conducting radio frequency signals using multiple layers. In some implementations, a signal transfer element configured to passively transfer RF signals between a first region and a second region includes a first conductor layer having a first continuous conductor configured as a first portion of a first antenna, a transmission line, and a first portion of a second antenna. The first antenna and the second antenna are configured to wirelessly receive and transmit Radio Frequency (RF) signals. The signal transfer element also includes a second conductor layer having a second continuous conductor configured as a second portion of the first antenna, a ground plane, and a second portion of the second antenna. The first conductor layer and the second conductor layer are spatially proximate such that the transmission line and the ground plane are configured to passively transfer RF signals between the first antenna and the second antenna independent of an electrical connection between the first conductor layer and the second conductor layer.
