Dielectric rod radiating antenna

Claim 1

A BROAD BAND HIGH FREQUENCY ANTENNA COMPRISING, IN COMBINATION: A HOLLOW CONDUCTING BODY TERMINATING AT ONE END IN A CO-AXIAL CONNECTOR AND AT ITS OTHER END IN A SLEEVE IN CO-AXIAL ALIGNMENT WITH SAID CONNECTOR; A ROD MEMBER OF HIGH DIELECTRIC MATERIAL HAVING A CYLINDRICAL SECTION RECEIVED WITHIN SAID SLEEVE AND ROTATABLE THEREIN, THE REMAINING PORTION OF SAID ROD EXTENDING FROM THE END OF SAID SLEEVE IN AXIAL ALIGNMENT THEREWITH; A PROBE CO-AXIALLY DISPOSED WITHIN SAID BODY HAVING ONE END CONNECTED TO THE INNER CONDUCTOR OF SAID CONNECTOR AND ITS OTHER END TERMINATING IN A LATERALLY BENT PORTION IN JUXTAPOSED RELATIONSHIP TO THE BASE OF SAID CYLINDRICAL SECTION, SAID LATERALLY BENT PORTION BEING BENT LESS THAN 90 DEGREES WITH RESPECT TO THE AXIS OF SAID BODY TO FORM AN ACUTE ANGLE WITH THE PLANE OF SAID BASE, THE EXTREME END OF SAID BENT PORTION BEING CONNECTED TO SAID BODY; AND A CONDUCTIVE COATING SURROUNDING THE EXTERIOR CYLINDRICAL SURFACE OF THAT PORTION OF SAID CYLINDRICAL SECTION OF SAID ROD WITHIN SAID SLEEVE, SAID COATING EXTENDING OVER A CIRCUMFERENTIAL EDGE PORTION OF SAID BASE AT THE END OF SAID CYLINDRICAL SECTION TO PROVIDE A SECTOR SHAPED COATING ON SAID BASE, SAID SECTOR SHAPED COATING BEING DEFINED BY CONVERGING EDGES OF SAID COATING EXTENDING FROM SAID CIRCUMFERENTIAL EDGE PORTION TOWARDS THE CENTRAL AXIS OF SAID ROD, SAID LATERALLY BENT PORTION AND SAID SECTOR SHAPED COATING CONSTITUTING A COUPLING FOR TRANSFERRING ELECTROMAGNETIC ENERGY PASSED INTO SAID CONNECTOR TO SAID ROD MEMBER, SAID ROD MEMBER SERVING AS A DIRECTIVE LENS FOR SAID ELECTROMAGNETIC ENERGY, ROTATION OF SAID ROD MEMBER THROUGH SMALL ANGLES LESS THAN THE ANGLE OF CONVERGENCE OF SAID SECTOR SHAPED COATING SERVING TO VARY THE POSITION OF SAID SECTOR SHAPED COATING WITH RESPECT TO SAID LATERALLY BENT PORTION OF SAID PROBE TO TUNE SAID COUPLING FOR MAXIMUM POWER TRANSFER, AND ROTATION OF SAID ROD MEMBER OVER NINETY DEGREES SERVING TO ALTER THE MODE OF EXCITATION OF SAID ELECTROMAGNETIC ENERGY IN SAID ROD MEMBER TRANSFERRED FROM SAID CONNECTOR TO SAID ROD MEMBER.
