Course detail
Antennas and Lines
FEKT-BPA-ANTAcad. year: 2022/2023
Mobile communication systems are based on the propagation of electromagnetic waves in the environment. Waves are transmitted and received by proper antennas. Antennas have to be completed by a suitable transmission line with high-frequency transmit circuitry and receive one. Wave propagation, antennas and transmission lines can be numerically modeled in computer programs. Lectures are aimed to present the described topics to the beginners in the field.
