Electromagnetic bandgap resonators synthesized using ceramic injection molding

Abstract A temperature‐compensated high‐performance BaZn 1/3 Ta 2/3 O 3 microwave substrate has been inductively loaded with metallic posts to realize an electromagnetic bandgap device with a 5‐GHz bandgap. Capacitive gaps inserted in the device create resonances in the bandgap that are 1/20 the size of standard distributed designs. Simulation and measurement of the bandgap structures agree to 20 GHz. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:371–375, 2014
