During the period covered by this report, investigations to extend the determination of the interference characteristics of U. S. Army communication equipment to include the case emission and susceptibility characteristics have continued. The major emphasis during this period has been on the development and evaluation of broadband, balanced, circularly-polarized antennas for use in measurements of the interference characteristics of communication equipment in shielded enclosures. The design, fabrication, and evaluation of 1 a conical loghelix antenna, 2 a circularly-polarized log-periodic antenna, 3 a crossed bow-tie antenna, and 4 a hooded antenna are discussed. These antennas were designed to operate in the 200 Mc to 1000 Mc range. Techniques for extending the use of these antennas to lower frequencies are discussed. Author
