Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
82 words
IN AN ANTENNA RANGE FOR ANTENNA MEASUREMENTS, MEANS FOR EMITTING A WAVE FRONT, A FIRST PARABOLLIC SURFACE CONTAINED WITHIN A WAVE GUIDE, AND A SECOND PARABOLIC SURFACE, SAID MEANS FOR EMITTING A WAVE FRONT, SAID FIRST PARABOLIC SURFACE, AND SAID SECOND PARABOLIC SURFACE BEING POSITIONED WHEREBY A WAVE FRONT EMITTED BY SAID MEANS FOR EMITTING A WAVE FRONT IS REFLECTED FROM SAID FIRST PARABOLIC SURFACE TO SAID SECOND PARABOLIC SURFACE AND SUBSEQUENTLY FROM SAID SECOND PARABOLIC SURFACE TO AN ANTENNA BEING TESTED.
Claim 2
Dependent Claim
82 words
IN AN ANTENNA RANGE FOR ANTENNA MEASUREMENTS, MEANS FOR EMITTING A WAVE FRONT, A FIRST PARABOLLIC SURFACE CONTAINED WITHIN A WAVE GUIDE, AND A SECOND PARABOLIC SURFACE, SAID MEANS FOR EMITTING A WAVE FRONT, SAID FIRST PARABOLIC SURFACE, AND SAID SECOND PARABOLIC SURFACE BEING POSITIONED WHEREBY A WAVE FRONT EMITTED BY SAID MEANS FOR EMITTING A WAVE FRONT IS REFLECTED FROM SAID FIRST PARABOLIC SURFACE TO SAID SECOND PARABOLIC SURFACE AND SUBSEQUENTLY FROM SAID SECOND PARABOLIC SURFACE TO AN ANTENNA BEING TESTED.
Claim 3
Dependent Claim
157 words
AN ANTENNA RANGE PROVIDING A WAVE FRONT INCIDENT UPON AN ANTENNA BEING TESTED, SAID ANTENNA BEING TESTED HAVING AN APERTURE WITH A MAXIMUM APERTURE DIMENSION AND SAID ANTENNA RANGE COMPRISING A PARABOLIC REFLECTING MEANS POSITIONED TO PLACE SAID ANTENNA BEING TESTED RELATIVELY CLOSE TO AND WITHIN THE PERIMETER OF SAID PARABOLIC REFLECTING MEANS, SAID PARABOLIC REFLECTING MEANS HAVING A FOCAL POINT; AND AN EMITTING MEANS FOR EMITTING A SPHERICAL WAVE FRONT TOWARD SAID PARABOLIC REFLECTING MEANS, SAID EMITTING MEANS BEING POSITIONED AT SAID FOCAL POINT SO AS TO DIRECT SAID WAVE FRONT TO A SMALL PORTION OF SAID PARABOLIC REFLECTING MEANS WHICH IS DISPLACED FROM ANY EDGE OF SAID PARABOLIC REFLECTING MEANS BY A DISTANCE SUFFICIENT TO SUBSTANTIALLY ELIMINATE EDGE EFFECT; WHEREBY A PLANE WAVE IS RADIATED FROM SAID PARABOLIC REFLECTING MEANS TOWARD SAID ANTENNA BEING TESTED AND THE APERTURE OF SAID PLANE WAVE IS SUBSTANTIALLY EQUAL TO SAID MAXIMUM APERTURE DIMENSION OF SAID ANTENNA BEING TESTED.
Claim 4
Dependent Claim
157 words
AN ANTENNA RANGE PROVIDING A WAVE FRONT INCIDENT UPON AN ANTENNA BEING TESTED, SAID ANTENNA BEING TESTED HAVING AN APERTURE WITH A MAXIMUM APERTURE DIMENSION AND SAID ANTENNA RANGE COMPRISING A PARABOLIC REFLECTING MEANS POSITIONED TO PLACE SAID ANTENNA BEING TESTED RELATIVELY CLOSE TO AND WITHIN THE PERIMETER OF SAID PARABOLIC REFLECTING MEANS, SAID PARABOLIC REFLECTING MEANS HAVING A FOCAL POINT; AND AN EMITTING MEANS FOR EMITTING A SPHERICAL WAVE FRONT TOWARD SAID PARABOLIC REFLECTING MEANS, SAID EMITTING MEANS BEING POSITIONED AT SAID FOCAL POINT SO AS TO DIRECT SAID WAVE FRONT TO A SMALL PORTION OF SAID PARABOLIC REFLECTING MEANS WHICH IS DISPLACED FROM ANY EDGE OF SAID PARABOLIC REFLECTING MEANS BY A DISTANCE SUFFICIENT TO SUBSTANTIALLY ELIMINATE EDGE EFFECT; WHEREBY A PLANE WAVE IS RADIATED FROM SAID PARABOLIC REFLECTING MEANS TOWARD SAID ANTENNA BEING TESTED AND THE APERTURE OF SAID PLANE WAVE IS SUBSTANTIALLY EQUAL TO SAID MAXIMUM APERTURE DIMENSION OF SAID ANTENNA BEING TESTED.
