When viewed from the side, the radiation pattern of a patch antenna and Yagi antenna can be described as follows:
Patch Antenna: The radiation pattern of a patch antenna is typically described as being doughnut-shaped or sometimes referred to as a toroidal shape. This is because the electromagnetic energy radiates perpendicular to the surface of the antenna, forming a torus shape around the antenna. This pattern is usually relatively flat, with the majority of the energy radiating outwards from the side of the patch.
Yagi Antenna: The radiation pattern of a Yagi antenna can be described as being conical. This is because the antenna elements are arranged in a specific pattern to create a focused beam of electromagnetic energy in a specific direction. The Yagi antenna typically has a narrow beam width in the H-plane, which is perpendicular to the direction of the elements, and a wider beam width in the E-plane, which is parallel to the direction of the elements.
To summarize, the radiation pattern of a patch antenna is typically doughnut-shaped, while the Yagi antenna has a conical pattern. It is important to note that the exact shape and characteristics of the radiation pattern will vary depending on the specific design and configuration of the antenna.
