Radiation Pattern Reconfigurable Horn Antenna Based On Parasitic Layer Concept, Mehmet Tanagardi
Radiation Pattern Reconfigurable Horn Antenna Based On Parasitic Layer Concept, Mehmet Tanagardi
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In recent years, multi-functional reconfigurable antennas (MRA) has attracted much attention in wireless communication. The reconfigurable antenna can adapt itself with changing system conditions, and it can provide different multi-functionalities which can give better system performances. Instead of using multiple antennas, a single reconfigurable antenna can provide the same performance and occupy less space. By using the parasitic layer technique, an antenna can be turned into a reconfigurable antenna. The main objective of this thesis is to study radiation pattern reconfiguration of the horn antenna by using the parasitic layer concept. The MRA consists of a single horn, dielectric loaded …
Analog Adaptive Calibration For Arbitrary Phased Array Configuration, Mark William Nielson
Analog Adaptive Calibration For Arbitrary Phased Array Configuration, Mark William Nielson
Theses and Dissertations
The development of phased array antenna systems requires considerable resources and time. Due to this constraint, the Naval Air Command (NAVAIR) needs a phased array that can be physically reconfigured to meet the demands of multiple missions without added development time or cost. This work develops and demonstrates a solution to this problem by implementing an adaptive calibration approach to the development of electronically steerable antennas (ESAs). In contrast to previous analog adaptive beamformer systems, this system allows for an arbitrary antenna configuration with a variable number of antenna elements and locations. A simulation model of arbitrary phased array configurations …
