Numerical Investigation of the System-Matrix Method for Higher-Order Probe Correction in Spherical Near-Field Antenna Measurements

Figure 2

The higher-order test probe with its reference point at (𝜃₀,𝜙₀) on the scan sphere of radius 𝑅. The output of Port no. 1 is 𝑉⁽¹⁾(𝜃₀,𝜙₀)=𝐸_𝜃(𝑅,𝜃₀+𝜓,𝜙₀), and the output of Port no. 2 is 𝑉⁽²⁾(𝜃₀,𝜙₀) given by (19).
