ABSTRACT:
Apparatus for exciting electrodeless lamps. A magnetron for generating electromagnetic energy in the microwave region includes an extension for its antenna terminal. The extension extends the length of the antenna to control the phase of loading on the magnetron. A circular ground flange and perforated screen enclose the electrodeless lamp, permitting microwave energy to excite the gas within the lamp, while confining the energy to the space bounded by the perforated screen and cylindrical ground flange. The extension for the antenna has a length which maintains the reflection coefficient phase to a level which does not adversely disturb the magnetron operating frequency.
