    Abstract

    An important antenna design goal is to have a dipole-like antenna operating close to a metallic groundplane (structure or platform). Unfortunately, the characteristics such as radiation resistance and bandwidth reduce dramatically as the antenna approaches closely to the ground plane. However, if the antenna could be matched even to the low radiation resistance, the gain increases as the antenna gets closer to the ground plane assuming low antenna ohmic losses. For low-loss ferrite nanoparticle composite backed ground planes, completely opposite behavior occurs in that the radiation resistance and bandwidth increase as the dipole moves closer. In the practical world an antenna should include a matching circuit to prevent serious mismatch loss to circumvent lower realized gain that would result for the unmatched case.
