PERTURBATION OF EMC MICROSTRIP PATCH ANTENNA FOR PERMITTIVITY AND PERMEABILITY MEASUREMENTS

By D. C. Kulkarni and V. Puri

Abstract:
The complex permittivity and permeability of barium hexaferrite in the 8-12 GHz range was determined by using perturbation of electromagnetically coupled Ag thick film patch antenna due to overlay. In this technique even minor change in the overlay material properties changes the antenna response. The power gain of the EMC patch antenna was enhanced by 50% due to barium hexaferrite overlay. Barium hexaferrite was synthesized by co precipitation method and their fritless thick films were fabricated by screen printing technique. The properties were found to depend on the synthesis conditions such as Fe/Ba molar ratio, pH of the solution.
