CLAIMS What is claimed is: 1. A melt processable thermoplastic composite comprising: 10 to 90 vol% a thermoplastic polymer based on a total volume of the thermoplastic composite comprising: (a) a poly(aryl)etherketone, a polysulfone, a poly(phenylene sulfide), a poly(ether imide), a poly(amide imide), a fluoropolymer, a polyolefin, a liquid crystalline polymer, or a combination comprising at least one of the foregoing; or (b) a polystyrene, a poly(phenylene ether), or a combination comprising at least one of the foregoing; 10 to 90 vol% a dielectric filler based on a total volume of the thermoplastic composite having a multimodal particle size distribution; wherein the dielectric filler comprises a first plurality of particles having a first average particle size and a second plurality of particles having a second average particle size; wherein the first average particle size corresponds to the peak of the first mode and the second average particle size corresponds to the peak of the second mode and wherein the first average particle size 1s 10 to 20 times the second average particle size; wherein the dielectric filler comprises titanium dioxide, barium titanate, strontium titanate, silica, corundum, wollastonite, boron nitride, aluminum oxide, aluminum nitride, silicon carbide, beryllia, magnesia, or a combination comprising at least one of the foregoing; and 0.5 to 5 vol % of a flow modifier based on the total volume of the thermoplastic composite; wherein the thermoplastic composite has a dielectric constant of greater than or equal to 5 at S00 MHz to 10 GHz and a dielectric loss of less than or equal to 0.007 at 500 MHz to 10 GHz. 2. An article comprising the melt processable thermoplastic composite of Claim 1, wherein the article optionally comprises a conductive layer disposed on at least one side of the melt processable thermoplastic composite. 3 The article of Claim 2, wherein the article is an antenna. 4. A method of forming an article comprising: injection molding, extruding, or layer-by-layer printing the melt processable thermoplastic composite of Claim 1.
