Active Non-Foster-based Magneto-Electric Antenna

The basic magneto-electric antenna is modified by the inclusion of a non-Foster negative inductor. Full-wave simulations showed that this modification allows a reduction in both antenna thickness and antenna footprint by a factor of 1/25 and 1/4, respectively. Additional circuit-theory simulations using a simple single-pole negative inductance model showed that the proposed antenna can operate in both stable mode (RX/TX) and self-oscillating mode with a frequency tuning range of 1:1.3.
