Abstract

This paper deals with electromagnetic interference radiated from air-conditioner piping that acts as an antenna and emits electromagnetic noise. The current distribution on the piping is measured by using a near-field magnetic probe, and the distribution mode is analyzed. The results show that the piping resonates at the frequencies where the piping length accords with λ/4, 3λ/4, and 5λ/4, and radiates electromagnetic noise as a monopole antenna. This radiation mechanism is confirmed by simulations using the CST EMC Studio electromagnetic field simulator.
