摘要: This communication presents practical implementations of small antennas using magneto-dielectric (MD) materials. We first describe the manufacturing process MD materials with a low-loss property (tan δm <; 0.1) up to 2 GHz. With this material as substrate, miniaturized handset are developed and radiation performances compared dielectric substrate antenna. The measured results show that required volume chip antenna is minimized 25 mm × 5 3 at cellular frequency bandwidth better antennas. In addition, loaded designed improve performance conventional on plastic carriers.
