Antennas serve as crucial transitional structures between guided electromagnetic energy (like in transmission lines) and the free space through which radio waves propagate [1, 2]. Understanding how they radiate energy is fundamental to antenna theory, and two key concepts in this understanding are **radiation patterns** and **directivity**. Radiation Patterns An **antenna radiation pattern**, also known as an **antenna pattern**, is defined as a **mathematical function or a graphical representation of the radiation properties of the antenna as a function of space coordinates** [3]. These properties are typically determined in the **far-field region** and are represented based on **directional coordinates** [3]. The radiation properties of concern include **power flux density, radiation intensity, field strength, directivity, phase, or polarisation** [3]. The radiation pattern primarily describes the **two- or three-dimensional spatial distribution of radi...
