Rapid Response Design for Extremely Low-Frequency Magnetoelectric Antennas Based on Out-of-Band Attenuation
Portable magnetoelectric antennas (MEAs) are widely utilized in close-range trans-media communication and detection applications due to their high efficiency, strong penetration capability, and remarkable miniaturization. However, under the mechanical excitation mechanism, the magnetic induction intensity and the symbol rate (SR) of the MEA present a mutually exclusive situation. In this letter, a rapid response design of an extremely low-frequency MEA based on out-of-band attenuation is proposed to enhance the SR while maintaining a constant magnetic induction intensity. When the MEA switches states, the proposed design utilizes the signals with frequencies higher than MEA’s operating band to accelerate the damping dissipation, thereby considerably reducing the response time of the MEA. Experimental results demonstrate that with additional power consumption, the response time is reduced by 37.43%, and the SR is increased from 0.056 Bd to 0.089 Bd.
期刊介绍:
IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
