Abstract
An electrodeless HID lamp formed with a power balanced coupling structure is disclosed. Microwave transmission to the discharge capsule is divided into two channels having an electrical length differential of about a half wave length. A balancing strap line is coupled between the two transmission lines where they deliver power to the field applicators for the discharge capsule. The strap line balances the power delivery between the two ends of the discharge tube.
