Patent Images
1. An antenna array comprising:
- an active element;
a plurality of controllable passive elements, each one comprising;
a dielectric substrate having a first and a second portion;
a conductive surface disposed on said first portion of said dielectric substrate;
wherein said second portion of said dielectric substrate comprises a connecting arm substantially perpendicular to said first portion;
wherein the distal end of said connecting arm is joined to said active element so as to form a deformable union therebetween.

Abstract
A foldable antenna includes a plurality of passive elements radially spaced apart from a center active element. The radial passive elements are joined to the active element to create a deformable union. In this way, the surrounding passive elements can be folded toward the midplane of the antenna array to create a relatively compact stored configuration.
