ABSTRACT
ABSTRACT
An ever-increasing demand for wider bandwidths in communication, radar, and imaging
systems has emerged. In order to facilitate this growing demand, progressive research
into millimeter-wave technologies has become vital in achieving next generation networks
such as 5G. Being cost e ective and easy to manufacture, Substrate Integrated Waveguide
(SIW) circuits have been demonstrated as a viable candidate for high-frequency
applications due to their low-loss, high quality-factor, and high power-handling
capabilities.
Research on beam-forming networks, especi cally the Butler matrix, has demonstrated
powerful beam-steering capabilities through the use of passive component networks.
Through these clever con gurations, a cost e ective and robust option is available for us
to use. In order to further millimeter-wave research in this area, this talk presents a
modified con figuration of the Butler Matrix in SIW that is physically reconfi gurable; by
separating the Butler matrix from the antenna array at a pre-selected point, the array
can be easily interchanged with other 1-dimensional, and 2-dimensional slot antenna
arrays. Although this system does not fall under the rigorous de finitions of Recon gurable
Antennas, it should be noted that the inter-changeability of 1 and 2 dimensional arrays
is not typically expressed in Butler matrix con figurations. Design and simulations are
carried out in CST Microwave Studio to inspect individual components as well as system
characteristics. Circuit prototypes are then manufactured and tested in an anachoic
chamber to validate simulation results and the design approach.
