Abstract:
1. A device for radiating to a medium or receiving from the medium, a signal having a predetermined wavelength in the medium, comprising: a body of a substance in which an antenna is encapsulated, and in which the wavelength λ of the signal is less than in the medium, wherein a surface of the body forms a signal lens that directs energy of a signal according to an intended radiation or sensitivity pattern, wherein the antenna is a dipole with arms of approximately λ/4 in length in the substance, wherein the body has a pair of opposite sides, a pair of opposite ends, a top, and a bottom, and wherein the dipole extends between the ends of the body and is spaced from the sides and the top and bottom of the body by wavelength dimensions of about λ/8 to about 3λ/8 in the substance.
