How can you measure the gain of an RF antenna?
The gain of an RF antenna is a measure of how well it converts the input power into radiated electromagnetic waves in a given direction. It is an important parameter for evaluating the performance and efficiency of an antenna in wireless communication systems. However, measuring the gain of an RF antenna is not a trivial task, as it involves several factors and methods that need to be considered. In this article, you will learn the basics of RF antenna gain, the different types of gain, and the common techniques for measuring it in the laboratory and in the field.
