Microstrip line (MS) is commonly used as a calibrator for probe calibration. However, some issues need to be addressed high-frequency applications, such ripple and attenuation caused by the embedded part of calibrator. In this article, an ultrawideband de-embedding calibration method (DCM) magnetic field probes proposed. Two symmetric nonsoldering grounded coplanar waveguide (GCPW) calibrators, including Through Line standards, are solve de-embedded <inline-formula...
The electric field (E-field) probe has been widely used for electromagnetic interference diagnosis in IEC61967-3. But with the increase detection frequency, calibration error caused by box of calibrator cannot be ignored. traditional method (TCM) directly affects measurement results E-field probe. In this article, a de-embedding (DCM) is applied to two typical probes (Probe A and Probe B). DCM can compensate effect improve accuracy. Different from TCM using microstrip (MS) line as...
In symmetric two-port probing system, the measured electromagnetic field signals can be decoupled. However, in practical application, asymmetric problem is difficult to avoid. So correcting system significant achieve ultra-wide-band near-field measurement. this paper, a virtual network matching method (VNMM) proposed based on circuit model, which different from previous correction (or calibration) method. By setting network, transformed into then As new forward method, VNMM simpler and...
Calibration for asymmetry of the simultaneously electromagnetic near-field probing system is a good way improving performance two-port probe. The previous rotating asymmetric calibration method (RACM) based on microstrip line measurements at two directions 0° and 90° limited to 12 GHz. In this article, nonrotating (NRACM) proposed ultrawideband system. A four-port vector network analyzer highly symmetric grounded coplanar waveguide (GCPW) calibrator are used solve matrix in method. It only...
Solving the asymmetric problem is essential for an two-port electromagnetic near-field probing system (ATPS). In this article, advanced forward two-sided correction method (FTACM) has been proposed. Unlike traditional inverse calibration (IACM), it needs two independent excitations created by calibrator; solution process of FTACM and process. The only self-parameter ATPS, including <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">...
A four-port composite probe with a pair of symmetric cross-orthogonal loops has been verified to measure electric and magnetic fields simultaneously.

Abstract Simultaneous electromagnetic field probing system (SEMPS) has been popular in recent years. Herein, a simultaneous with Y‐shaped separation detection structure (SEMPS Y) is first proposed, which the electric region and magnetic of probe are separated by completely covering shield along loop adding pin‐shaped metal wire to capture field, not same as classical dual structure. Combined non‐rotating asymmetric calibration method (NRACM), 4‐port vector network analyser (VNA) highly...

Abstract An ultrawideband de‐embedding calibration method (DCM) for a dual probe is proposed in this paper. Different from the conventional (CCM), which microstrip calibrator and form three‐port network, system four‐port network. By using two different lengths of grounded coplanar waveguide (GCPW) calibrators, namely line‐kit through‐kit, de‐embedded ‐parameter model network obtained. Measured results show that ripple DCM with GCPW reduced by 59% CCM calibrator, phase delay has been almost...
