Design and Analysis of Millimeter Wave Patch Antenna for 5G6G Applications

Abstract

With the rapid developments in the field of communication vis-a-vis Antenna, there is always a need for new research and improved communication protocols and designs. In the field of antenna latest trends of research are following Fifth Generation (5G) and Sixth Generation (6G) communication systems. In depth literature review and analysis of a novel antenna is carried out in this thesis and based on this literature review a research problem is formulated. Major problems of 5G/6G antennas designs include low gain,narrow bandwidth, complex structure, complex feed design and multilayer structures. To solve the aforementioned problems a novel millimeter waves patch antenna is proposed. The antenna uses a unique shaped feeding mechanism of circular loop to feed multiple circular patch antennas at the same time. Three circular patch antennas are attached to the feeding structure. The patches are designed to radiate at different frequency within that required operating frequency band. The antenna targets a wide frequency band from 23.66 GHz to 28.73 GHz. The antenna achieves a measured peak gain of 11.96 dBi at 26 GHz while 9.5 dBi and 10.64 dBi at 24 GHz and 28 GHz, respectively along with a measured bandwidth of 16.93%. The proposed antenna has broadside radiation patterns in the operating frequency band. The proposed antenna finds application in the 5G and 6G mobile communication technologies.
