Preximity Effects for Parallel Rectangular Conductors in Non-Transmission-Line Mode

摘要

In applications of electrically short antennas such as multiturn loops, variation in ohmic losses due to proximity effects can significantly affect uncorrected estimates of efficiency. The paper investigates experimentally the proximity effects on the current distributions and associated ohmic losses for two identical parallel rectangular corss-section conductors as a function of separation distance and cross-section. The system is operated in a non-transmission-line mode. In the light of experimental results a first-order theory is developed and verified for analyzing relative proximity effects at the extremes of conductor separation distances. (Author)
