A study on magnetic near-field measurements above a patch antenna using an optical waveguide probe with a loop element

Abstract

We developed a magnetic field probe consisting of a LiNbO/sub 3/ optical waveguide modulator and a loop antenna element for accurate magnetic near-field measurements in the gigahertz range. We confirmed the probe invasiveness by measuring magnetic field distributions above a patch antenna operating at 2.49 GHz using the probe. Then we compared those… (More)
