There are several factors that can affect wave propagation, including:

A linear array consists of antenna elements arranged along a single straight line. Antenna and Wave Propagation by K

If you require step-by-step commonly found in academic exams.

The full PPT contents of "Antenna and Wave Propagation" by KD Prasad typically include:

component), the physical length is typically trimmed slightly to roughly Antenna Arrays The minimum distance from the transmitter

The electrical characteristics (gain, directivity, radiation pattern) remain identical whether the antenna transmits or receives. Fundamental Antenna Parameters

There are several types of antennas, including:

A radiation pattern is a graphical representation of the radiation properties of the antenna as a function of space coordinates.
