Radiation from Rhombic Antennas

A direct theoretical determination of the transmitting properties of the horizontal rhombic antenna and of the closely related inverted V structure has been made. Expressions are given for the intensity of the radiation, the polarization, the radiation resistance, and the gain. The intrinsic simplicity of the radiation distribution functions is revealed by graphical representation. Stereographic representation also supplements the analysis and provides clear insight into the effects available through variations of design, and enables the essential features of a specific design to be obtained for all directions with a very small amount of labor. Methods of diminishing the relative intensity of radiation from subordinate lobes are considered.
