Learning Outcomes of the course unitBy the end of the course, the students should be able to:
  1. Manage the fundamental properties of antennas (gain, input impedance, bandwith, directivity, mutual coupling etc) in order to construct a wireless communication link.
  2. Design an antenna array in order to achieve the required beamwidth for the desired specification and be able to use an antenna as part of a transceiver circuit.
  3. Analyze the fluctuation over time, season, weather of the maximum propagation range and the link quality in order to improve the performance of the designed system.
  4. Interpret the radio propagation conditions in a mobile or time variant environment considering the multipath, flat or frequency selective fading, using simple link budget models like Okumura or Hata models
  5. Compare the frequencies used for satellite communications and appraise the potential improvement in the system’s throughput, exploiting the concept of polarization and depolarization in satellite links, frequency reuse techniques and technical aspects for real life satellite communication applications such as satellite TV, GPS
  6. Justify the constantly increasing need for developing special interest topics, in wireless communications, such as PAN networks using UWB and WiMAX technologies or AdHoc sensor/RFID networks

Planned learning activities and teaching methods

The taught part of course is delivered to the students by means of lectures, conducted with the help of computer presentations. Lecture notes and presentations are available through the web for students to use in combination with the textbooks. The structure of the course teaching is based on lectures (3 hours per week) in a classroom. 

During the lectures several related exercises are solved on the board with participation of the students. Several problems are left unfinished for the students to complete at home. Other problems are used as assignments. Topic notes are compiled by students, during the lecture which serve to cover the main issues under consideration. Students are also urged to use the textbook assigned to the course. Related homework problems are also assigned from the textbook as a turn in assignment or for homework practice. Also, students are advised to use the reference books for further reading and practice in solving related exercises.
