Development in the Terahertz Communication System

Abstract

The dream of the receiver subsystems in a chip is even complete transceivers, makes the millimeter/terahertz wave region and MMIC technology development the key factor. The communication system designer must not only integrate the antenna and its associated circuits but also the phase shifter, amplifiers and control circuits. the use of integrated monolithic antennas fabricated in a single, high resolution, integrated circuit process offers the potential of closer dimensional accuracy, ruggedness, simplicity and better reliability and reproducibility in comparison to their hybrid counterparts, being excellent candidates for integrated quasi-optical power combining systems. In previous chapters, we have emphasized on the planar antenna technology and described various techniques to improve the directivity of the antenna. However, various methods including the use of the artificially engineered materials, frequency selective surface, thick substrate material have been discussed. In addition to this, it has been stressed to the application of the low-permittivity substrate material to improve the electrical performance of the antenna. In this chapter, we present a brief review of the terahertz communication system including its importance, the development in the field of the hardware, the channel propagating model, and different compunction systems developed for the terahertz communication.
