Abstract : The Miniloop is an HF loop antenna, which has found use on U.S. Coast Guard vessels. The antenna is a large diameter loop mounted on a pedestal. It is tuned with a variable capacitor mounted in series at the top of the loop. Inductive coupling from a much smaller loop on the lower rim is used as a feed. MININEC (NOSC TD 938), The New MININEC Version 3); a Mini-Numerical Electromagnetics Code, by J. W. Rockway and J. C. Logan, September 1986, is used to represent the Miniloop antenna mounted over a perfectly conducting ground plane. The development and validation of the MININEC model of the Miniloop will be discussed. A sample method for determining radiation efficiency will also be presented.
