In this paper, the effects of the DC bias lines on bowtie terahertz photomixer antenna are investigated, and a method, namely resistively loaded lines (RLL), is proposed to compensate the effects of the DC bias lines. The numerical results of the bowtie antenna show that RLL almost removes the effects of the bias lines compared to that of the commonly used bias line types, such as coplanar stripline and photonic bandgap type bias lines.
