• Description:
  This report covers antenna design, analysis, and development work performed for the U.S, Bureau of Mines under Purchase Order PO382223 by Terry S. Cory, P.E. The anticipated usage of the antennas and accompanying analysis is for medium frequency wireless communications in coal mines. The work has included a complete vehicular antenna design experience through the prototype development stage, design analysis and comparative tests to be useful in eventual development of optimized portable PA/antenna systems, and analysis of the coupling between vehicular antennas and existing mine wiring.
