Dual Band THz Antenna Using T Structures and Effect of Substrate Volume on Antenna Parameters

A dual band coaxial fed slotted microstrip patch antenna for THz application on FR4_epoxy substrate using T shape patches is designed and analysed. Slots are made by symmetrically cutting a copper sheet. Implementation of this structure offers a better directivity and radiation efficiency. Full wave simulation results showed that the THz band slot antenna works at 0.6326 THz and 0.8702 THz. Maximum gain is obtained as more than 8.2 dB. This THz slot antenna can be used for the application in various fields such as fast and secure data transferring, biomedical applications, radar and THz imaging, nanoantenna applications.
