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 planeantenna interface was also experimentally determined. Junction conditions such that there would be maximum currentminimum charge and minimum currentmaximum charge on the vertical monopole were examined. The effect on the input impedance and currentcharge 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.
