Abstract :
Thermal noise characteristics of a resistively-loaded vee dipole (RVD) are numerically analyzed using a commercial method of moments software. The RVD analyzed in this paper is loaded with 28 chip resistors. The resistors are loaded such that the resistors with higher values are placed farther from the drive point than the resistors with lower values. The results show that the resistors with lower values contribute more to the total noise power accepted by a 200 Omega feed line though the resistors with lower values generate smaller noise voltage.
