Abstract
Compact low-loss antennas and methods for long range two-way communication are provided. In one example, a mechanical antenna includes a first material having first embedded electric charge carriers, a second material having second embedded electric charge carriers, and an actuator coupled to at least one of the first material and the second material, the actuator being configured to generate a monopole current and transmit a low frequency signal by causing kinematic motion of the first material relative to the second material.
