Charge and Current Distributions on, and Input Impedance of Moderately Fat Transmitting Crossed-Monopole Antennas
Abstract
Charge and current distributions in the vicinity of the cross junction for several configurations of electrically long, moderately fat crossed-monopole transmitting antennas over a ground plane were measured and compared with the equivalent monopole. The input impedance of these configurations at the ground plane/antenna interface was also experimentally determined. Junction conditions such that there would be maximum current/minimum charge and minimum current/maximum charge on the vertical monopole were examined. The effect on the input impedance and current/charge distribution of adding resonant and antiresonant horizontal cross members to the junction was investigated and displayed. For purposes of physical understanding, a zero-order explanation was given in terms of the multiple resonances present on the crossed-monopole as compared with the reference monoploe.
