Anand, Mayur Sudesh Darak, D. Sriram Kumar Graphical abstract Summary: This plot shows that the antenna return loss (S11) of the graphene based optically transparent terahertz patch antennas with and without MWCNT short. By shorting the microstrip line and ground plane of the antenna with a MWCNT via, the return loss of the antenna is improved. It is observed that return loss of −48.75dB is obtained for MWCNT loaded antenna as compared to -39.37dB obtained for without MWCNT loaded antenna. Return loss improvement of 9.38dB is achieved for antenna loaded with MWCNT. Thus by optimizing the position of the MWCNT short return loss of the antenna is significantly improved for the same impedance bandwidth. Both the graphene based transparent antennas are achieved the −10dB impedance bandwidth of 12.83%. The graphene based transparent antennas have broad bandwidth (12.83%), high directivity (7.56dB) and high gain (≥2dB). The proposed antennas overcomes the limitations of the conventional transparent patch antennas in terms of −10dB impedance bandwidth (<5 %) and gain (<2dB).
