BROADBAND TRANSMITTING ANTENNA

THERE IS A GREAT NEED FOR HF BROADBAND TRANSMITTING ATENNA FOR COMMUNICATIONS AND JAMMING APPLICATIONS. THE MAJOR DISADVANTAGES OF PRESENT NARROW BAND ANTENNAS ARE: SLOW TUNING COUPLERS LIMIT JAMMING SYSTEM RESPONSE TIME AND OPERATIONAL BANDWIDTHS; TO ACHIEVE RESONABLE EFFICIENCIES LARGE ATENNA STRUCTURES ARE REQUIRED, ESPECIALLY AT THE LOWER FREQUENCIES; REQUIRE GOOD GROUND CONDUCTIVITY TO MAINTAIN REASONABLE EFFICIENCIES. ASTRON CORPORATION HAS INVESTIGATING ADVANCED INNOVATIONS/TECHNIQUES, WHICH WHEN JUDICIOUSLY COMBINED, WILL ACHIEVE A FAMILY OF BROADBAND TRANSMITTING ATENNAS WHICH CAN OPERATE OVER FREQUENCIES OF 1 TO 30 MHX (WITH POTENTIAL FOR EXTENSION TO 400 MHZ) AND WHICH CAN MEET THE REQUIREMENTS OF SMALL MAN-PECK, JEEP, VAN, AND AIRBORNE SYSTEMS. THE ASTRON INNOVATIONS/TECHNIQUES INCLUDE SLOW WAVE, MULTI-FILAR, HIGH CURRENT, ANCILLARY ELEMENTS, MULTI-RESONANT/ LENGHT AND EM PROPRIETARY STRUCTURES. EACH OF THESE TECHNIQUES WILL BE EVALUATED BY COMPUTER SIMULATION AND LABORATORY TESTS.
