Radiation and Antennas: System Aspects

This lecture covers the propagation characteristics of radiation and antennas, including the power balance for multiple carriers, the use of parameters for digital and analog transmissions, and examples illustrating concepts such as effective isotropic radiated power (EIRP). The instructor explains the relationship between directivity and sensing surface, the reciprocity of powers, and the concept of energy per bit to noise power spectral density ratio at the receiver. Various antenna types and their ideal characteristics are discussed, along with practical examples demonstrating the application of theoretical concepts.
