In-plane Textile Electronics: Selection of Optimum Operation Bands

The paper summarizes experience with electromagnetic interference (EMI) noise background measurements on the board of aircraft EVEKTOR EV-55 in the development phase. Measurements were aimed to select optimum frequency bands for the operation of on-board textile-integrated electronics. The EMI background was measured in four places situated along the center of the aircraft body. Measurement scenarios comprised several aircraft operation conditions like the running engine, power only on batteries, transmission on the radio etc. The appropriate industrial scientific medical (ISM) communication channel at 5.8 GHz was selected due to the lower noise interference and acceptable dimensions of textile-integrated microwave components.
