摘要

This paper presents a novel wideband and high directivity Bowtie photoconductive antenna (PCA) for THz frequency applications. The radiation properties of proposed PCA were analyzed by varying important design parameters, such as substrate thickness, conductor thickness, bowtie antenna width, length and gap. The optimized values of these parameters are then used to design a wideband PCA THz antenna which exhibits impedance bandwidth of 3 THz, 3 dB AR bandwidth of 6 THz, peak directivity of about 18.2 dBi and peak radiation efficiency of 98% within the operating band. To improve the directivity of the proposed antenna, a silicon-based lens is added in the structure and the effect of silicone lens on THz antenna directivity is also studied for enhanced directivity of proposed antenna. The proposed THz antenna can be a prospective candidate for future THz applications such as spectroscopy, imaging, sensing and indoor communication.
