Abstract:
Dual‐band ferrite chip antenna having 105 mm 3 of volume was fabricated with Ba 3 Co 2 Fe 24 O 41 (Co 2 Z)‐glass composite and antenna performance was evaluated. The permeability and permittivity of the composite were in the range of 1.92–2.12 and 7.33–7.45, respectively, from 1.575 to 2.45 GHz. Magnetic and dielectric loss tan δ of Co 2 Z‐glass composite was 〈 3.5% in the 1.5–3.0 GHz range. The 3D average gain and bandwidth of the 40h‐shake‐milled and sintered Co 2 Z‐glass composite antenna were −1.27 dB and 355 MHz at 1.575 GHz, −4.08 dB and 270 MHz at 2.45 GHz, respectively. Simulated S ‐parameter spectrum is in good agreement with experimental results. © 2010 Wiley Periodicals, Inc.
