Multifunctional Reconfigurable Antennas And Arrays Operating At 60 Ghz Band, Abdurazag Mohamed Khalat May 2017

Multifunctional Reconfigurable Antennas And Arrays Operating At 60 Ghz Band, Abdurazag Mohamed Khalat

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In this digital era, the demand for faster, reliable, and adaptive wireless communication systems is increasing. Various factors can affect the signal propagation in the wireless medium, such as weather, broadcast environment, physical obstructions, etc. This study aims to improve the antenna performance by means of dynamically altering its properties so that it can adapt to different environments and communication scenarios. This study is not resorting in a traditional antenna design, but rather explores an alternative approach known as the multifunctional reconfigurable antennas (MRAs). Unlike its predecessor, i.e., legacy antennas, MRAs can dynamically change its operation frequency, radiation pattern, and …


Beam Steerable Reconfigurable Antenna With Smart Rf Switching On 3d Parasitic Level, Mohammad Ababil Hossain May 2017

Beam Steerable Reconfigurable Antenna With Smart Rf Switching On 3d Parasitic Level, Mohammad Ababil Hossain

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Traditional antennas have a lot of limitations as their performance is usually fixed by their initial geometry. On the other hand, modern communication systems are getting way to complicated compared to their earlier counterparts. This necessitates some special types of smart or reconfigurable antennas, which can dynamically adapt to the requirements of the communication systems more effectively. Using conventional single functional antennas is therefore not an efficient approach in these sort of communication systems. Considering all these factors, in this thesis, a beam steerable reconfigurable antenna system is presented that can yield the radiation patterns of multiple antennas with a …
