Analysis Of Optically Transparent Antennas Designed From Different Transparent Conductors, Rakib Hasan
Analysis Of Optically Transparent Antennas Designed From Different Transparent Conductors, Rakib Hasan
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This master’s thesis work presents an investigative study about the performance of transparent antennas. The antennas have been fabricated using two advanced transparent conductive films (TCF) namely Nano-C Hybrid and Silver-Nanowire (AgNW). Nano-C Hybrid is a new transparent conductive film which combines thin conductors like Carbon Nanotube and Silver Nanowire. The antennas made from Nano-C Hybrid and AgNW are of monopole types and are mounted on a ground plane made out of a printed circuit board and the antennas are excited using an SMA connector through that printed circuit board. Simulation works have been performed to find out the optimum …
Two Types Of Conformal Antennas For Small Spacecrafts, Salahuddin Tariq
Two Types Of Conformal Antennas For Small Spacecrafts, Salahuddin Tariq
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Spacecraft and vehicular bodies often require antennas that are conformal to their surface. The advantage of this choice is that they do not suffer from air drag or breakage and can be formed into any desirable shape. We can make them to operate at those frequencies at which simple wire antennas will require considerably longer length. Our thesis is about conformal antenna design for two space projects. The first project involves an array of patch antennas placed on multi-layer cylindrical substrate. Four of these antennas are S-band and four of them are GPS-band antennas. The second project deals with the …
Digital Microfluidics As A Reconfiguration Mechanism For Antennas, Yasin Damgaci
Digital Microfluidics As A Reconfiguration Mechanism For Antennas, Yasin Damgaci
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The properties of conventional antennas are fixed by the initial design and cannot be changed. A reconfigurable antenna, on the other hand, can dynamically change its properties, and it can adjust its behavior for a given propagation condition. This dissertation work concentrates on novel reconfiguration technologies, including design, microfabrication, and characterization aspects with an emphasis on their applications to multifunctional reconfigurable antennas. In the literature, reconfigurable antennas have made use of various reconfiguration techniques. The most common techniques utilized revolved around switching mechanisms. Other techniques such as the incorporation of variable capacitors, varactors, and physical structure manipulation surfaced recently to …
Integrated Solar Panel Antennas For Cube Satellites, Mahmoud N. Mahmoud
Integrated Solar Panel Antennas For Cube Satellites, Mahmoud N. Mahmoud
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This thesis work presents an innovative solution for small satellite antennas by integrating slot antennas and solar cells on the same panel to save small satellite surface real estate and to replace deployed wire antennas for certain operational frequencies. The two main advantages of the proposed antenna are: 1) the antenna does not require an expensive deployment mechanism that is required by dipole antennas; 2) the antenna does not occupy as much valuable surface real estate as patch antennas. The antenna design is based on using the spacing between the solar cells to etch slots in these spaces to create …
