Abstract :
Properties of electromagnetic field radiation due to micro gap discharge were examined in experimental study. An experimental system was consisted to measure the radiated electromagnetic waves in the frequency range from 1 GHz to 3 GHz using a pear of spherical electrode and a horn antenna. As a result, the amplitude of received voltage is proportion to the discharge voltage (charged voltage of the electrode) from 300V to 620V, and proportion to the diameter of spherical electrodes. Furthermore, a directivity of EM radiation from a pair of spherical electrode is highest at the front of electrode of 0 degree, on the one side received voltage shows lowest amplitude in side of electrode of 90 degree.
