摘要

提出了一种在光子带隙(PBG) GaAs衬底上生长的太赫兹偶极子天线。利用理想的PBG结构减小了GaAs衬底厚度对效率和主光束方向的影响。仿真结果表明，在较高的输入阻抗下，上半空间的指向性可达到8.7 dBi。

Terahertz dipole antenna performance enhancement using a photonic-bandgap GaAs substrate

A terahertz dipole antenna grown on a photonic-bandgap (PBG) GaAs substrate is presented. The desired PBG structure is utilized to reduce the thick GaAs substrates effects on the efficiency and the main beam direction. Simulated results show that a directivity of 8.7 dBi can be achieved in the upper half space with a considerably higher input impedance.
