Abstract: Described herein is an apparatus and a method for a cluster connector. The cluster connector comprises at least three coaxial-cable core conductors formed in an additive manufacturing process; a dielectric around each of the three coaxial-cable core conductors, formed in the additive manufacturing process; a metallic shield around each dielectric, formed in the additive manufacturing process; at least one stub on each metallic shield, formed in the additive manufacturing process; and a common ground connection connected to each metallic shield, formed in the additive manufacturing process.

Abstract: A spiral antenna device includes a plurality of generally polygonal loops. The polygonal loops have respective side counts that decrease progressively as a function of the loop's radial distance from a center of the antenna device. The side count may vary between loops as a multiple of a power of two.

Abstract: A monocone antenna includes a volumetric radiation element having a feed point at a vertex of the volumetric radiation element being connected to a feed transmission line and a capacitive ring radially outside of the volumetric radiation element and in proximity to the volumetric radiation element. The capacitive ring is connected to a ground plane for the monocone antenna.
