Performance Characterization of A Patch Antenna Embedded Partially by Magnetized Ferrite Material

This paper discusses the performance characterization of a patch antenna which is embedded partially by magnetized ferrite within the host material. The substrate used as a host material is Rogers RO4003C configured in triple layers of structure. An external magnetic bias is applied using a magnetic field source aiming to magnetize the ferrite material. Measurement results show that the partially embedding of magnetized ferrite within the host material could affect the resonant frequency and S-parameter response.
