ABSTRACT:
Low-loss power combining-transmitting antenna arrangements are disclosed which are suitable for use in power distribution systems employing RF transmission of the energy being distributed and other applications in which it is necessary to coherently combine and transmit several RF signals. The disclosed arrangements utilize slot radiators that are excited at each end by separate feed lines. Narrow, nonradiating slots extend outwardly from the ends of each radiating slot to provide impedance matching. One modular arrangement includes amplifier circuitry for supplying the antenna excitation signals and phase error correction circuits for maintaining proper signal phase through the antenna module.
