Rectangular waveguides were most former type of transmission lines employed to carry microwave signals and about which a great deal is known. In this paper, the electric field intensities of dipole probe and rectangular waveguide probe with infinite ground plane is analyzed and compared to that of no probe instance. A standard 2.296 x 1.016cm WR-90 open ended rectangular waveguide with infinite ground plane of operating frequency of 9GHz is used as a radiator. The dependency of normalized electric field intensity in the near field to the separation between the radiator and probes was observed. The effect of rotation of waveguide probe in the aperture plane (y-axis) was also studied. The simulations were performed using AnsoftÃ¢â?¬â?¢s HFSS.
