1. A biconical antenna assembly for electromagnetic compatibility testing, the biconical antenna assembly comprising:
an antenna feed point;
a first antenna structure and a second antenna structure, wherein the first antenna structure and the second antenna structure extend from the antenna feed point towards opposite directions; and
at least one capacitive structure that is in addition to inherent capacitances of components of the biconical antenna assembly, wherein the at least one capacitive structure is attached to a most distal point of the first antenna structure or the second antenna structure from the antenna feed point, wherein the at least one capacitive structure has a three-dimensional geometry such that the capacitive structure is different than a disc or a plate that terminates the respective antenna structure,
wherein the at least one capacitive structure has an ellipsoid shape or a spherical shape.
