A firstresonance frequency is determined by the length of the rectangular microstrip antenna.
第一谐振频率由矩形微带天线的长度所决定。

An L-shaped band elimination filter on the T-shaped joint part is also used for restricting the resonance of the frequency multiplication of the firstresonance frequency.
位于T形接合部上的L形带阻滤波器亦用来抑制第一谐振频率的倍频的谐振。

IBM physicists built the first microscope based on that approach, dubbed magnetic resonance force microscopy (MRFM), in 1993.
