1. A self-deployable antenna comprising:
a flexible base substrate having a network of conductive traces, wherein a portion of the network of conductive traces is arranged in an overlap pattern on a first side and a second side of the flexible base substrate and formed into a plurality of transmission lines, wherein the overlap pattern on the first side and the second side are configured with a set misalignment, wherein the plurality of transmission lines are connected to a plurality of receptive and transmission elements, and wherein the flexible base substrate is compactible between a compacted configuration and a deployed configuration such that in the deployed configuration the flexible base substrate is flat; and
a structural substrate having a resilient body with a first end and a second end, where the first end is connected to the flexible base substrate, wherein a portion of the flexible base substrate containing a portion of the network of conductive traces is connected to a portion of the resilient body and wherein the structural substrate is deployable between the compacted configuration and the deployed configuration,
wherein in the compacted configuration the resilient body of the structural substrate is positioned parallel to a plane of the flexible base substrate,
and wherein in the deployed configuration the resilient body of the structural substrate is positioned out of plane from the plane of the flexible base substrate,
wherein the resilient body of the structural substrate is placed under stress through application of a holding force when in the compacted configuration such that when in the deployed configuration the holding force is removed and the resilient body of the structural substrate self-articulates to the deployed configuration; and
wherein the portion of the network of conductive traces is configured to send and receive a signal.
