Abstract

The demand for higher wireless communication speed and latency has been increasing over the past decade. As the LTE frequency has found its maturity in terms of bandwidth spectrum, exploration of new frequency bands is critical to addressing the capacity demand in the future. Terahertz (THz) technology is one of the promising solutions to provide higher bandwidth capacity, data rates and interference-free from other wireless legacy frequency spectrum for the next generation applications such as Internet of Things (IoT). However, the development of THz wave's detector is still a challenging issue to the date due to its unique radiation characteristic between millimeter wave and infrared domains as well as its complexity issues in very small wavelength. A bolometer can be considered as THz signal detector by converting the received THz waves into heat and further transformed into electrical signals by the thermistor. In this research, we designed an antenna-coupled microbolometer as THz wave receiver. An analysis base on the dissipated energy of the bolometer is conducted to find the optimum energy absorption in which the impedance of the bolometer will be matched with the antenna. The simulation results show that an optimum matching condition can be obtained by considering maximum dissipated energy in higher bolometer resistance.
