First Claim
1. An antenna assembly for a spatial coupler, the antenna assembly comprising:
- a core member comprising;
a cylindrical core portion extending longitudinally between a first end and a second end of the antenna assembly, the cylindrical core portion defining an outer core diameter; and
a plurality of core fins extending radially outwardly from the cylindrical core portion, each of the plurality of core fins tapering from a first height at the first end of the antenna assembly to a second height smaller than the first height at the second end of the antenna assembly; and
a shell member disposed around the core member, the shell member comprising;
a cylindrical shell portion extending longitudinally between the first end and the second end of the antenna assembly, the cylindrical shell portion defining an inner shell diameter; and
a plurality of shell fins corresponding to the plurality of core fins to form a plurality of fin pairs, the plurality of shell fins extending radially inwardly from the cylindrical shell portion, each of the plurality of shell fins tapering from a third height at the first end of the antenna assembly to a fourth height smaller than the third height at the second end of the antenna assembly,wherein each fin pair of the plurality of fin pairs forms a tapering channel therebetween, the tapering channel having a first channel height at the second end of the antenna assembly and a second channel height at the first end of the antenna assembly, the second channel height smaller than the first channel height.

Abstract
A spatium amplifier includes a plurality of amplifiers connected between a pair of spatial couplers, each having a core member and a shell member forming an antenna. The core member includes a cylindrical core portion and a plurality of tapering core fins extending radially outwardly from the cylindrical core portion. The shell member includes a cylindrical shell portion and a plurality of tapering shell fins extending radially inwardly from the cylindrical shell portion to form a plurality of fin pairs. Each fin pair forms a tapering channel having a first channel height at a first end of the antenna and a second channel height larger than the first channel height at a second end of the antenna. Each of the plurality of amplifiers is electromagnetically coupled to a respective fin pair at the first end of each of the antennas.
