摘要：Mg1-xCdxCo0.05Fe1.95O4 ferrites are proposed for high frequency radar antennas, where x varies with the value of 0.0, 0.2, 0.3 and 0.4. With 5 wt% Bi2O3 added for low temperature co-fired ceramic (LTCC) application, the spinel ferrites synthesized at 930 degrees C reveal fairly excellent magnetic and dielectric properties. X-ray diffraction indicates the processed samples present normal spinel peaks and Bi24Fe2O39 (BFO) peaks. The existing BFO tailors the real part of magnetic permeability (epsilon') and dielectric permittivity (mu') to be approximately equal (x = 0.4, epsilon' approximate to mu' approximate to 26) at a wide frequency range from 1 MHz to 100 MHz. Meanwhile, the LTCC-processed samples have ultra low dielectric loss tan delta(epsilon) and magnetic loss tan delta(mu) (tan delta(epsilon) approximate to 0.0008, tan delta(mu) approximate to 0.03, x = 0.3). In addition, the high saturation magnetization and appropriate coercivity mean enhanced magnetization. These eminent magneto-dielectric characteristics enable the materials to possess a farther study-worthy necessarity.
