摘要

这项工作探索了直接解决阻抗失配问题的可能性，在设计和建模中采用高阻抗天线的连续波光电混合器，基于保守的设计规则和材料选择。提出了两种来自折叠偶极子的天线设计，并将其与现有器件的已发表结果进行了比较，结果显示输出功率提高了4.6 dB。讨论了实现集总元素匹配网络的可能性。

Improving output power of terahertz heterodyne photomixer by impedance matching

This work explores the possibilities of directly addressing the impedance mismatch problem in the design and modelling of a continuous wave photomixer employing high impedance antennas, based on conservative design rules and material choices. Two antenna designs derived from the folded dipole are presented and compared to published results from an existing device showing an improvement of up to 4.6 dB in output power. The possibilities of implementing a lumped element matching network are discussed.
