AN OPTIMIZED ULTRA LOW FREQUENCY SHIELDED-LOOP ANTENNA

Abstract

The design and construction are described of an optimized rectangular shielded-loop antenna employed as the receiving antenna for reception of VLF (20 kc) standard frequency broadcasts from the National Bureau of Standards, Boulder, Colorado. The receiving site is located at Redstone Arsenal, Alabama. This design affords an approximate 60 per cent increase in effective height with a 3-db increase in terminal output voltage over a conventional loop antenna. The antenna will tune from 14 to 34 kc and can be optimized at any frequency within this band with the proper value of gap loading. A current bibliography of loop antenna literature is also available.
