| The piezoelectric device improves on the efficiency limits of small, conventional metal antennas without sacrificing bandwidth. Prototype 9.6 cm long lithium niobate transmitting antenna operates at 35 kHz and may be 300 times as efficient as a similarly sized conventional antenna. https://physicstoday.scitation.org/doi/10.1063/PT.3.4244 |
