This paper describes a non-contacting method of achieving near-field to far-field transformation using Kirchhoff surface integral representation (KSIR).The advantages of this method include that it is possible to distinguish the six fields independently on the basis of each individual integral surface and at the same time simplify the formula calculations. A patch antenna, chosen to be the device under test, was fabricated on an FR4 with a height of 0.9mm to assist with near-field to far-field transformation and operated at a center frequency of 2.4GHz. We used a non-contacting measurement device called EM-ISIGHT, by APREL Inc., to measure the near-field radiation of the patch antenna. Combining the near-field data and the KSIR to extract the far-field radiation of the DUT was the principal transformation methodology. We verified the accuracy of the methodology by comparing the relation between electric intensity versus distance and electric intensity on the far-field surface. |
