Design and analysis of a millimeter wave full-duplex antenna

Abstract

As wireless technologies continue to evolve, we all want faster internet and more data on our devices. The current 4G networks were created to meet these demands, but they are no longer enough to handle the increasing number of users and their need for faster speeds. That is why we are transitioning to a new type of wireless communication called 5G, which will use a higher frequency called millimeter-wave (mm-wave) spectrum. This will help us achieve even faster internet access and support the growing number of devices that need to connect to the network. To fulfill the demanding data rate and better utilization of the frequency bands full-duplex is one of the growing techniques. In the conventional communication system, either signal can be transmitted or received on the same channel, whereas in an in-band full-duplex (IBFD) antenna, transmitting and receiving of the signal take place simultaneously at a single frequency. The objective of this thesis is to design and analyze millimeter wave full-duplex antenna. This thesis covers the study of fundamentals of antennas and microstrip patch antenna. In this thesis a two-port microstrip patch antenna system with significant isolation enhancement (60dB), which can be deployed for Full-duplex transceiver systems.
