“…The important features of microstrip antenna e.g., low-profile, low-weight, low-cost, easy integrability into arrays or with microwave integrated circuits have made it popular as transmit and receive antenna in modern microwave systems. Numerous researchers had worked on different applications of planar microstrip structures [8][9][10][11][12]. However, the authors have not noticed any work reported on the performance evaluation of microstrip patch antenna as EMI sensor.…”

Abstract-This paper presents the result for antenna factor of microstrip patch antenna when used as electromagnetic interference (EMI) sensor. Antenna factor is an important parameter of a sensor used for EMI measurements. The microstrip antenna has found wide application as transmit and receive antenna in modern microwave systems. In this paper, a new application of microstrip antenna as EMI sensor is presented. The result for antenna factor versus frequency of a microstrip patch antenna is presented using commercial software CST Microwave Studio. Also the experimental results for a prototype antenna are presented and compared with the simulated result.

Abstract-An analysis method for electromagnetic field coupling to microstrip line connected with nonlinear components is proposed in this paper. Different from the published work, not only the voltage and current response of the nonlinear component connected to the transmission line (TL) can be obtained, but also the power transmitted from this nonlinear component to the next one at both the fundamental frequency and harmonics can be predicted. The proposed method suitably combines the classical field-to-TL coupling theory and the nonlinear large-signal scattering parameters on the basis of a black box model in frequency-domain. Then this method is experimentally validated by a laboratory system including a microstrip line connected with a simple nonlinear component constituted by the anti-paralleled HSMS-282C Schottky diodes pair welded to a 50 Ω microstrip line. The calculated results using the proposed method show good agreement with the measured data.

Abstract-A model for the two-dimensional analysis of microstrip lines, named Rigorously Coupled Multi-conductor Strip (RCMS) is introduced. In this model, the width of the strip of a microstrip line is subdivided into a large number of rigorously coupled narrow strips. So, a microstrip line can be considered as a coupled multi-conductor transmission line. Determination of the capacitance and inductance matrices of the model is introduced, also. The voltages and currents induced by electromagnetic fields for the coupled multi-condutor strips problem can be obtained using Bernardi's method. The effect of an external EM wave on a microstrip line with non-uniformity in its width is computed by adding the circuit model of transverse discontinuity (narrow slit) to the RCMS model. Finally, the validity and efficiency of the introduced method is investigated using previous work and full wave EM-simulation software.
