Synchronization and Combining of the Radiation Powers of Active Microwave Antennas Integrated with Field-Effect Transistors

摘要

Combining of the powers of microwave generators designed as a array of log-periodic antennas on a dielectric substrate and field-effect transistors as active components is experimentally investigated. Possibilities of a substantial increase in the generation efficiency due to mutual synchronization of radiators are demonstrated, and conditions for formation of the radiation pattern are studied.
