摘要

In this paper, a simple equivalent circuit model has been proposed for Ti-Au photoconductive dipole antenna to analyse its intensity modulation and radiation characteristics. The photocurrent and the terahertz emission intensity obtained using the proposed circuit model is verified using numerical method. Further, the equivalent circuit model is integrated with an electromagnetic tool to analyse its radiation characteristics and the photoconductive antenna is found to provide a directivity of 5.89 dBi at 1.58 THz. Intensity modulation of terahertz radiation is analysed using the equivalent circuit model by applying a bias voltage in the form of pulses. The modulated photocurrent output would produce the corresponding emission intensity which can be used for terahertz data transmission.
