Abstract

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.

基于带外衰减的极低频磁电天线快速响应设计

便携式磁电天线以其高效、强穿透能力和显著的小型化特点，在近距离跨媒体通信和探测领域得到了广泛的应用。然而，在机械激励机制下，MEA的磁感应强度和符号率（SR）呈现互斥的情况。在这封信中，提出了一种基于带外衰减的极低频MEA快速响应设计，以提高SR，同时保持恒定的磁感应强度。当MEA切换状态时，利用频率高于MEA工作频带的信号加速其阻尼耗散，从而大大缩短了MEA的响应时间。实验结果表明，在增加功耗的情况下，响应时间缩短了37.43%，SR从0.056 Bd提高到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.
