MODIFICATION TO MININEC FOR THE ANALYSIS OF WIRE ANTENNAS WITH SMALL RADIUS TO WAVELENGTH RATIO

Abstract

MININEC is a useful and compact method of moments antenna program, but MININEC does not give reasonable values for the input reactance of very thin wires at low frequencies. This problem greatly restricts the use of MININEC in the design and analysis of VLF and LF antennas. A modification to the program which eliminates this restriction is discussed. The modification consists of treating both the source and observation segments as filaments and only considering the wire radius when computing the self-impedance. A listing of the changed computer code is included. [Vol. 1, No. 1, pp. 29-31 (1986)]
