Electromagnetic wave radiation has been widely developed and applied for various wireless systems. Among the electromagnetic spectrum bands, Terahertz (THz) band wireless technologies are considered as the promising future wireless systems for providing large bandwidth. Detection such high frequencies are quite challenging due to its characteristics is in between electronics and optics domain. Antenna, which has been the main techniques for lower frequency bands, can be applied to this particular region. However, a tiny wavelength contributes more complexities in design and develop THz systems. The bolometer technique has offered a solution to electromagnetic wave radiation detection by converting electromagnetic waves energy to heat. In this research, we discuss a combination between an antenna and a bolometer to obtain an effective electromagnetic wave radiation detection, especially on the impedance matching effect. We consider a bowtie antenna working at a resonant frequency of 1 THz. The bolometer is modeled for matching to the antenna input impedance of 50Ω. The combination design is simulated by using CST Microwave Studio. The simulation results show that the matching condition is obtained if the input impedance of both the antenna and the bolometer are in the same situation. The use of an antenna and a proper matching condition can contribute to optimizing the power transfer through the antenna gain and low reflection loss, respectively.
