Abstract

An antenna formation device/method has been developed to create variable shaped antennas using predetermined interference patterns to expose and develop a photoresist layer that is etched on a substrate to form the structure corresponding to the desired variable shaped antenna.

Claims

1. An antenna shaping device comprising:

depositing means for depositing a photoresist layer on a substrate on a moveable support;

illuminating means for illuminating the photoresist with light intensity from plural sources producing a predetermined interference pattern thereon to expose said photoresist;

developing means for developing the photoresist;

etching means for etching the photoresist and substrate to form a structure having a contour corresponding to the interference pattern; and

forming means for using the structure to form an antenna.
