These problems become more challenging for cases when an array of antennas are needed such as for correlation interferometers that provide high spatial resolution of Earth and space. The proposal will specifically examine the potential applicability of novel fiber-based antennas to L-band radiometry for the purpose of generating high resolution soil moisture and sea surface salinity data. Initial estimates indicate that a x10 improvement on resolution may be possible with long fiber-based antenna arrays. Lincoln Laboratory has been investigating the ability to produce large flexible RF antenna arrays embedded in polymer fibers. These lightweight fibers are flexible enough to be coiled and uncoiled, thus facilitating transport and deployment. The metal that forms the antenna structure and other conductive elements is embedded inside a polymer boule that is heated and drawn to form a novel type of fiber. The resulting fiber thus has multiple materials embedded inside for the ability to support sensing capabilities and other functionalities. Thus, this fiber fabrication process may also lead to a cost-effective means to create very large antennas. This work will include analysis of the required antenna performance and the ability of fiber-based antennas to meet those requirements, deployment strategies, satellite specifics, space tolerance of components and materials, a preliminary system-level design, and concept of operations.<\/p>\n\n\n\n<p><strong><a href=\"\/general\/niac-2024-selections\">2024 Phase I Selection<\/a><\/strong><\/p>\n\n\n<div id=\"\" class=\"hds-topic-cards nasa-gb-align-full maxw-full width-full padding-y-6 padding-x-3 color-mode-dark hds-module hds-module-full wp-block-nasa-blocks-topic-cards\">\t\t<div class=\"grid-container grid-container-block-lg padding-x-0\">\n\t\t\t<div class=\"grid-row flex-align-center margin-bottom-3\">\n\t\t\t\t<div class=\"desktop:grid-col-8 margin-bottom-2 desktop:margin-bottom-0\">\n\t\t\t\t\t<div class=\"label color-carbon-60 margin-bottom-2\">Keep Exploring<\/div>\n\t\t\t\t\t<h2 class=\"heading-36 line-height-sm\">Discover More NIAC Topics<\/h2>\n\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t\t\t<div class=\"grid-row grid-gap-2 hds-topic-cards-wrapper\">\n\t\t\t\t\t<a href=\"https:\/\/www.nasa.gov\/space-technology-mission-directorate\/\" class=\"mobile:grid-col-12 tablet:grid-col-6 desktop:grid-col-3 topic-card margin-bottom-4 desktop:margin-bottom-0\">\n\t\t\t\t<div class=\"hds-topic-card hds-cover-wrapper cover-hover-zoom bg-carbon-black\">\n\t\t\t\t\t<div class=\"skrim-overlay skrim-overlay-dark skrim-left mobile-skrim-top padding-3 display-flex flex-align-end flex-justify-start z-200\">\n\t\t\t\t\t\t<div>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<p class=\"hds-topic-card-heading heading-29 color-spacesuit-white line-height-sm margin-top-0 margin-bottom-1\">\n\t\t\t\t\t\t\t\t<span>Space Technology Mission Directorate<\/span>\n\t\t\t\t\t\t\t\t<svg viewBox=\"0 0 32 32\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><circle class=\"color-nasa-red\" cx=\"16\" cy=\"16\" r=\"16\"><\/circle><path d=\"M8 16.956h12.604l-3.844 4.106 1.252 1.338L24 16l-5.988-6.4-1.252 1.338 3.844 4.106H8v1.912z\" class=\"color-spacesuit-white\"><\/path><\/svg>\n\t\t\t\t\t\t\t<\/p>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t<figure class=\"hds-media-background  \"><img loading=\"lazy\" decoding=\"async\" width=\"525\" height=\"800\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/12\/stmd.jpg?w=525\" class=\"attachment-1536x1536 size-1536x1536\" alt=\"\" style=\"transform: scale(1);
