Engineered Metamaterials Enable Remarkably Small Antennas

Caption

This Z antenna tested at the National Institute of Standards and Technology is smaller than a standard antenna with comparable properties. Its high efficiency is derived from the "Z element" inside the square that acts as a metamaterial, greatly boosting the signal sent over the air. The square is 30 millimeters on a side.
