文章简单介绍了磁棒天线的结构分类及其工作原理

AM Antenna Requirements 1: Effective Inductance of antenna seen by AMI pin needs to be between 180 uH and 600 uH 2: Effective Quality Factor (Ql) of antenna higher the better, but you get the diminishing return beyond 150 because the on-chip capacitor Qc is about 100 at 1MHz 3: Effective terminal stray capacitance seen by AMI by the antenna should be small, our recommended antennas are in the 8pF range.
