1. Measurements, Estimations and Calibration with a Fully Digital Array
University essay from Uppsala universitet/Signaler och systemAbstract : In modern digital communication, transmission and reception of information through electromagnetic signals requires digital devices that can process high data rates accurately despite being located in information heavy environments. One type of antenna receiver is the digital antenna array, which can steer its lobes electronically to increase or decrease sensitivity in specific directions. READ MORE

2. Ray Tracing Algorithm for Dielectric Domes
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Almost hemispherical scanning capabilities are required for modern wireless communication systems to produce broad coverage without performance degradation. Phased array antennas are commonly used as a fully-electronic beam-steering solution for its rapidity in beam switching. READ MORE

4. Scanning range extension by combining arrays with lenses
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Array antennas, and more specifically phased array antennas, are widely used in radar detection and communication systems because of their excellent beam scanning ability and simple control. Generally speaking, the scanning function can be realized in two ways: mechanically or electronically. READ MORE

5. Dual-polarized fully-metallic Vivaldi antenna array in a triangular lattice
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : New mobile communication generations need electromagnetic sensors capable of steering their high-directive beams towards the users. Conventional base stations use square lattice phased arrays to accomplish this task. These arrays are composed of a large number of radiating elements to achieve the required high directivity and scanning capabilities. READ MORE
