Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
135 words
A POWER TRANSMISSION SYSTEM COMPRISING, GENERATING MEANS FOR PROVIDING AN ELECTROMAGNETIC WAVE OF A PREDETERMINED FREQUENCY, AN ACTIVE POWER SPLITTER OF THE RESONANT CAVITY TYPE FOR DIVIDING SAID ELECTROMAGNETIC WAVE INTO A PLURALITY OF SIGNAL PORTIONS OF SAID PREDETERMINED FREQUENCY, MEANS FOR COUPLING SAID GENERATING MEANS TO SAID SPLITTER, A PLURALITY OF RADIATING ELEMENTS ARRANGED IN AN ARRAY, A POWER AMPLIFIER OF VARIABLE GAIN CONNECTED BETWEEN EACH OF SAID RADIATING ELEMENTS AND SAID SPLITTER TO PROVIDE AN AMPLIFIED SIGNAL PORTION TO EACH OF SAID RADIATING ELEMENTS, SAID SPLITTER BEING ADJUSTABLE TO PROVIDE A PROPER IMPEDANCE MATCH FOR SAID AMPLIFIERS, AND A POWER LEVEL BRIDGE ASSOCIATED WITH EACH OF SAID POWER AMPLIFIERS TO CONTROL THE GAIN THEREOF AND MAINTAIN A DESIRED CONSTANT SIGNAL LEVEL AT SAID RADIATING ELEMENTS REGARDLESS OF THE MAGNITUDE OF SAID SIGNAL PORTION.
