1. A neural interface, comprising:
- a housing configured to be implanted at a location in a patient under a skull and proximate neural tissue, the housing having a longitudinal axis;
a first antenna within the housing and configured to transmit neural data wirelessly to an external device;
a second antenna within the housing and configured to transmit neural data wirelessly to the external device,wherein the first antenna and the second antenna transmit the neural data on the same or an overlapping frequency spectrum,wherein the housing comprises shielding partially surrounding the first antenna and second antenna,wherein the housing comprises one or more shielding-free windows, each shielding-free window comprising a window axis parallel to the longitudinal axis of the housing, the shielding-free windows configured to allow the first antenna and the second antenna to allow wireless transmission at angles between perpendicular to the window axis and aligned with the window axis.

Abstract
A device system and method for wirelessly communicating through tissue is provided. The device system comprises an implanted device with an array of antennas aligned with a tandem device with an array of antennas outside of the body. The two devices wirelessly communicate in a bi-directional manner. The implanted device can act as a physiological sensor and stimulator, and the external device can act as a controller and relay. Such configurations allow for a range of uses within research and clinical settings.
