1. An antenna module, comprising:

  • a composite dielectric body including at least one ceramic dielectric inclusion composed of at least one material selected from the group consisting of materials having a relative dielectric permittivity ≧

    10 and materials having a relative dielectric permeability ≠

    1, the at least one ceramic dielectric inclusion embedded in a dielectric host material selected from the group consisting of amorphous silica, titania, tantalates, pure alumina, admixtures thereof, and an organic media such that the composite dielectric body has an effective permittivity ≧

    4;

    a metallization layer adjacent the composite dielectric body and including a ground plane and at least one contact pad; and

    at least one electrically conductive element disposed parallel to the metallization layer and electrically connected with the at least one contact pad, each conductive element disposed relative to the composite dielectric body such that the conductive element is resonant over a band of frequencies and has a length that is ≦

    50% of the length that would be required to maintain the same resonance without the composite dielectric body.
