Abstract
A dipole array antenna includes a conducting substrate, a feeder layer, and a dipole layer. The feeder layer is spirally formed by etching a first thin film on the foamed dielectric layer. The feeder layer is placed on a conducting substrate and a connector is attached to the feeder layer. The dipole layer is placed on a second foamed dielectric layer deposited on the feeder layer so as to prevent the energy loss of the feeder layer by etching a second thin film.

A dipole array antenna, comprising:
- (a) a first foam dielectric layer deposited on a conducting substrate;
- (b) a first thin film layer deposited on said first foam dielectric layer;
- (c) a spirally shaped feeder element formed on said first thin film layer and having respective ends;
- (d) a connector attached to one of said ends;
- (e) a second foam dielectric layer deposited on said feeder element so as to prevent the energy loss of said feeder element;
- and
- (f) a second thin film layer deposited on said second foam layer and including a plurality of dipoles formed thereon.
