ABSTRACT:
A thin film resonator (TFR) antenna is disclosed which is characterized by substantially lower effective dielectric constant for the layer of dielectric material deposited between the ground metal layer and the top metal layer (transducer) of the TFR antenna. The dielectric constant is substantially lowered by forming an array of dielectric posts in the dielectric layer. The posts support the top metal layer of the TFR antenna. The interstices between the posts are occupied by air in the preferred embodiment. The lower effective dielectric value results in reduced ohmic losses which in turn leads to enhanced gain in the TFR antenna system.
