The term "antenna radiation pattern" is defined as a geometric representation of the relative electric field strength as emitted by a transmitting antenna at different spatial locations. For example, a radiation pattern can be represented pictorially as one or more two-dimensional cross sections of the three-dimensional radiation pattern. Because of the principle of reciprocity, it is known that an antenna has the same radiation pattern when used as a receiving antenna as it does when used as a transmitting antenna. Therefore, the term radiation pattern is understood herein to also apply to a receiving antenna, where it represents the relative amount of electromagnetic coupling between the receiving antenna and an electric field at different spatial locations.
