This lecture focuses on the system aspects of antennas, exploring how to use antenna parameters in telecom systems. It covers different types of noise, such as external interference and internal electronic noise, and explains how to calculate noise power. The lecture delves into the concept of noise figure, emphasizing the importance of low noise amplifiers in reducing noise effects in a system. It also discusses the equivalent noise temperature of antennas and how it varies based on the antenna's orientation. The lecture concludes by examining the impact of noise in wireless communication systems and the modulation of signals to carry information, highlighting the key components and the overall link budget.
