摘要

提出了一种减小手机耳机扬声器附近天线感应电磁场的技术，从而提高助听器的兼容性。通过在底盘边缘的每个长边引入谐振四分之一波短路传输线，底盘的耳机扬声器部分与天线部分实现了电去耦。通过仿真和实测验证了该方法的有效性。

Improvement of hearing aid compatibility (HAC) of terminal antennas using wavetraps

A technique for reducing the antenna induced electromagnetic fields in the vicinity of the earpiece speaker in mobile phones is presented, thereby improving the hearing aid compatibility (HAC). By introducing resonant quarter-wave short-circuited transmission lines to each long side of the chassis edges, the earpiece speaker section of the chassis is electrically decoupled from the antenna section. The proposed technique has been validated through simulations and measurements.
