Design and review of terahertz antennas

With the rapid development of wireless cellular communication from 1G to 5G, it is about to enter the 6g era, not only are people more connected, but more and more smart devices have also realized the Internet, and this trend will continue until 2030 and beyond, when everything will be smart Internet anytime, anywhere. If smart devices can sense their surroundings and share environmental information with other smart devices, then this connection will become more intelligent. This paper introduces the core technology of future 6g wireless communication, the terahertz antenna in the equipment part of terahertz communication, and carries on the design of a new terahertz antenna, which is mainly used for transmitting and receiving terahertz signals, and can effectively convert electromagnetic wave energy into wireless signals to realize wireless communication with other devices. The design and performance of terahertz antennas directly affect the transmission efficiency and reliability of terahertz communication systems. In addition, the role of the new terahertz antenna model can expand the application field of terahertz technology and promote the wide application of terahertz technology in communication, security, medical and measurement fields.
