摘要: A long-term evolution (LTE) MIMO ferrite antenna was fabricated on Ni0.5Mn0.2Co0.07Fe2.23O4 substrate (14 × 7 3 mm3) and characterized for performance. Measured return loss isolation were -26 -16.4 dB at 720 MHz, respectively. Correlation coefficient calculated from experimental S-parameters (S11, S22, S12, S21) less than 0.02 in the LTE band. Three-dimensional peak gain 746 MHz measured to be -8.83 dBi 1 -8.32 2. These low gains are attributed high magnetic of substrate. Performance simulation suggests that can further improved up -3.14 with use low-loss ferrite.
