Abstract

A dual-band patch antenna operating in the Terahertz regime is presented.By loading the double T-type radiation slots

the surface current path on the patch is modified

which results in the dual-band operation of the antenna.Simulation results indicate that the designed antenna can operate on the bands of 300 and 670GHz simultaneously with a maximum gain of7.13 dB.Featured with a simple structure

easy fabrication and stable performance

the dual-band antenna can be applied in Terahertz communication systems.The proposed design scheme has certain significance to the design of dual-band patch antenna.
