Measured and simulated electric, magnetic, and thermal field distributions of a patch antenna operating at high power Conference Paper

abstract

• Electric, magnetic, and thermal field distributions in the near field of a microstrip patch antenna operating at high RF power are experimentally determined. Electro-optic sampling is used to obtain the electric field distribution, magneto-optic sampling provides the magnetic field distribution, and semiconductor bandgap thermometry is used to obtain the thermal field. Measurements are compared with simulations and are found to be in good agreement. From the measurements, it is concluded that dielectric loss, in the substrate of the structure, is the dominant loss mechanism in the antenna.
