Measurement of an antenna at Terahertz (THz) frequency is a key challenge in the field of micro and nano-wave research. The very small wavelength increase complexity during the fabrication and measurement processes. Therefore, it is necessary to develop a measurement technique to get reasonable results, such as radiation pattern, with an affordable measurement setting. In this paper, we study a scaling up process of a 1 THz planar bow-tie antenna intended to be measured at a desired resonant, which is determined at 1 GHz. The antenna is fabricated on a FR-4 material substrate and measured by conducting the common microwave antenna measurement. The radiation pattern of the scaled up antenna shows comparable result with the THz design antenna. Thus, this technique can be used as a solution to confirm radiation pattern of a THz antenna through the scaling up procedure and the microwave measurement.
