It is also called radiation pattern.Ī2: The power radiated from an Antenna per unit solid angle is called the Radiation Intensity.Ī3: It is a part of earth atmosphere, from about 85 km to 600 km altitude. It also explains how antenna receives energy. Pattern in graphical representation explains the the process of energy radiation of antenna out into space. Summary of Wave Characteristics in Different Frequency Ranges.Ī1: It is a graphical representation which represents the radiation properties of antenna (as a function of space). Relation between and Skip Distance, Multi-hop Propagation. Structure of ionosphere, Refraction and Reflection of Sky Waves by ionosphere, Ray Path, Critical Frequency, MUF, LUF, OF, Virtual Hlght and Skip Distance.
