The Gravitational Wave (GW) radiation pattern is derived that results from a rod rotating about a pivot, a dumbbell rotating about its central axis, a pair of stars rotating about their orbital focus, or a stationary circular asymmetrical‐array of tangentially jerking elements. The three‐dimensional shape of the GW radiation pattern is like a dumbbell cross‐section having its long axis perpendicular to the plane of motion or along the central axis of the stationary ring of sequentially jerking elements. The center of the radiation pattern is situated at the pivot, orbital‐focus, or center of the stationary array. Knowledge of the GW radiation pattern allows for optimum placement of a detector. In the case of High‐Frequency Gravitational Waves (HFGWs), in which the diffraction of the GW radiation is less than the dimensions of the ring of jerking elements, the radiation pattern is situated at the center of the ring and represents a focus or concentration point of the HFGWs, The concentration point extends over a diffraction‐limited spot having a radius of λGW/π, where λGW is the wavelength of the HFGW. In the case of a superconductor, prior research, although speculative has shown that the GW wavelength is foreshortened by a factor of about 300. Thus there could be a much more concentrated diffraction‐limited flux of HFGW at the focus. It is shown that the efficiency of a HFGW communications link could be approximately proportional to the sixth power of the HFGW frequency. Applications to space technology, involving aerospace communications, and Astronomy are discussed.
