BROADBAND HF/VHF ANTENNA SYSTEM

TO ACHIEVE THE PROGRAM GOALS OF ULTIMATELY FABRICATING AND DEMONSTRATING MINIATURIZED BROADBAND, HR/VHF ANTENNAS FOR USE ON AIR FORCE VEHICLES, THE TWO CRITICAL TECHNICAL ASPECTS OF THE PROBLEM, FORESHORTENING AND BROADBANDING, HAVE BEEN STUDIED, PROTOTYPE CONCEPTS DEVELOPED, AND ENGINEERIN FEASIBILITY ASSESSED IN AN EXTENSIVE PHASE I PROGRAM UNDERTAKEN BY ASTRON. REALIZATION OF THESE CONCEPTSREQUIRED ADDITIONAL COMPUTER MODELLING AND LABORATORY AND ANTENNA RANGE TESTING WELL SUITED TO A PHASE II EFFORT GOALSAND PURPOSE. THE CULMINATION OF THE PHASE II EFFORT WILL BETHE DELIVERY OF SEVERAL ENGINEERING MODEL ANTENNAS FOR EVALUATION OF ACTUAL AIR FORCE PLATFORMS.
