▎ 摘　　要

NOVELTY - An antenna comprises 1st phase (24) comprising greater than or equal to 1 polymer (20); 2nd phase (26) comprising greater than or equal to 1 1st component; and optionally, interface between 1st phase and 2nd phase, where interface has a concentration gradient of greater than or equal to 1 1st component in which concentration of greater than or equal to 1 1st component decreases with distance away from 2nd phase towards the 1st phase. At least one 1st component comprises greater than or equal to 1 functional component and/or greater than or equal to 1 functional precursor component, where the greater than or equal to 1 1st component, in combination with the greater than or equal to 1 polymer, has a high dielectric constant and/or a low dielectric loss tangent. The antenna is a functional antenna and/or a functional precursor antenna. USE - An antenna selected from planar antenna, three-dimensional (3D) printed antennas suspended in air, Vivaldi antenna, low loss suspended antennas, such as conformal helical antennas, electrically small suspended antenna coils, 3D suspended antenna feeding surface integrated waveguide (SIW) networks, ultra-large array (ULA) of antennas, frequency selective structures (FSS), and/or 3D suspended metasurfaces and conformal 3D reflect arrays, useful for 5G applications, such as a 2D or 3D printable antenna, preferably a 3D printable composite antenna which is optionally non-conducting (all claimed). ADVANTAGE - The antenna is suspended in air and has reduced signal losses; has high permittivity; and is physically smaller while maintaining electrical size. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) formulation for making an antenna which is capable of making an antenna having a low dielectric loss, a high gain, and/or tunable permittivities; (2) manufacture of an antenna which involves (a) combining greater than or equal to 1 1st component and greater than or equal to 1 polymerizable component to form the formulation and polymerizing the greater than or equal to 1 polymerizable component to form greater than or equal to 1 polymer, where greater than or equal to 2 phases are formed from the greater than or equal to 1 1st component and the greater than or equal to 1 polymer; and (3) use of the formulation for making an antenna. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the phase separation of a resin for silver/barium strontium titanate/polymer antenna. Formulation (10) Nanoparticles (18) Polymer (20) 1st phase (24) 2nd phase (26)
