Open TEM cell for electromagnetic compatibility testing of small‑scale radioelectronic devices

This paper presents the design and fabrication of an open TEM cell. It allows you to measure radiated emission immunity radioelectronic devices. The size EUT should not exceed 184×162×30 mm. Performed analytical quasi-static analysis regular part In frequency range up 1.4 GHz reflection coefficient |S11| does minus 45 dB. electrodynamic model cell is developed geometric parameters are optimized using a genetic algorithm. Analysis showed that in 920 MHz voltage standing wave ratio (VSWR) 1.3. inequality electric field area placement more than 6 dB 875 MHz. validity obtained results checked numerical methods finite elements transmission line matrix. A solid-state evaluate effect features assembly. dependences solid‑state do 17.69 916 fabricated by laser cutting bending aluminum sheet metal. Using vector circuit analyzer Micran R4M-18 measured S‑parameters |S21| 936 2.2 measurements Altera Cyclone IV FPGA debug board 1 with presented.
