Basic rhombic antenna

Basic rhombic antenna

A rhombic antenna can be made of two obtuse-angle V antennas that are placed side by side, erected in a horizontal plane, and terminated so the antenna is nonresonant and unidirectional. The antenna is placed end to end and terminated by a noninductive resistor to produce a uni-directional pattern.

Figure shows the individual radiation patterns produced by the four legs of the rhombic antenna and the resultant radiation pattern. The principle of operation is the same as for the V and the half-rhombic antennas.
