Antennas, Arrays & Calibration:  Beam Forming and Beam Steering

October 22, 2021 @ 1:30 pm - 3:00 pm

Antennas, Arrays & Calibration: Beam Forming and Beam Steering

Speaker: Prof. Dr. Levent Sevgi – IEEE APS Distinguished Lecturer – IEEE Fellow

The antenna is an electromagnetic (EM) radiator that emits radio frequency power. In other words, it is a transducer that converts voltage [V] to the electric field [V/m] (or vice versa). This IEEE AP-S DL talk will focus on electromagnetic radiators, antennas, antenna arrays and calibration. First, antenna as a transducer will be discussed and its circuit and electromagnetic models will be reviewed. Fundamental antenna terms and concepts will be summarized. Then, differences between communication and EMC antennas will be given. Finally, antenna calibration will be explained. In the second part, formation of antenna arrays will be presented and their beam forming and beam steering capabilities will be shown via a simple, MATLAB-based ARRAY virtual tool. Any 2D array (i.e., linear, planar, circular, etc.) may be designed by the user and its 2D and 3D radiation characteristics can be investigated using this tool. Beam forming capabilities for different locations, number of radiators, as well as for operating frequencies can be visualized. The package may be used as an educational tool in many undergraduate antenna lectures. It may also be used to validate and verify the finite-difference time-domain (FDTD) and method of moments (MoM) packages in public domain or, for example, the ones supplied in [3]. Moreover, the user may improve package and add novel features by using the supplied source codes.
