1. A method for constructing an antenna, comprising the following steps:

  • (a) fabricating a patch element onto a first substrate surface;

    (b) fabricating a ground plane onto a second substrate surface;

    (c) embedding an impedance transformer between abutting substrate layers between the patch element and the ground plane;

    (d) connecting a first end of the impedance transformer to a feed point on the patch element; and

    (e) connecting the outer conductor of a coaxial feed to the ground plane and the inner conductor of the coaxial feed to a second end of the impedance transformer.
