摘要

提出了一种基于衬底集成波导（SIW）的毫米波磁场探头。该探头包括用于检测的金属通孔和带状线以及SIW传输。在带状线和SIW之间使用锥形微带线进行场模传输和阻抗匹配。SIW在毫米波频段具有较低的传输损耗，能够维持磁探头的平整度和电场抑制。所提出的探针的频段为25 ~ 31 GHz。在工作频段电场抑制比大于20 dB，在29 GHz时电场抑制比可达35 dB。

A Novel Millimeter Wave Magnetic Probe Based on SIW Transmission Structure

A millimeter wave magnetic field probe based on substrate integrated waveguide (SIW) is proposed. The probe comprises a metal via and stripline for detection and a SIW transmission. A taper microstrip line is used between stripline and SIW for field mode transmission and impedance matching. The SIW has low transmission loss at millimeter wave frequency band, which can sustain the flatness and electric field suppression of the magnetic probe. The frequency band of the proposed probe is from 25 to 31 GHz. The electric field suppression ratio in the working band is over 20 dB, and can reach 35 dB at 29 GHz.
