摘要

This paper introduces electronic-beam switching graphene-strips leaky-waveantenna (GS-LWA) for THz wireless communications with different feedingstructures. The antenna is constructed from graphene-strips printed on siliconoxide substrate with total dimensions of 1350 × 300 × 35 μm~3. The graphenetunable conductivity is used to control the GSLWA radiated beam directionwithout changing its physical structure. A scanning range of 94° (from −68° to26°) is achieved at 2 THz using different codes. The effect of different planewave launchers on the radiation characteristics of GS-LWA is investigated. Aplanar substrate integrated waveguide horn antenna as a plane wave launcheris designed. It introduces a peak gain of 18.2 dBi with a bandwidth of 21.95%and SLL of 10.6 dB. End-fire radiation from parabolic reflector is employed tolaunch plane-wave in the GS-LWA. A matching BW of 0.82 THz is achievedwith peak gain of 18 dBi. A coplanar fed Yagi-Uda like structure element isstudied using a single element and two elements array. The two elements arrayprovided the highest matching of −40 dB over BW of 6% and gain of 16.5 dBi.Finally, tapered microstrip line is investigated. It introduced the lowest SLL−16.1 dB with a gain of 17.5 dBi and BW of 39.57% (from 1.5 to 2.24 THz). Theselection of proper feeding structure depends on the required matching BW,peak radiated gain, and the lowest SLL. Full-wave analysis of the GS-LWAlaunched by different feeding methods is introduced.
