Abstract: With the increasing expansion of the Internet of Things (IoT), the Internet of Vehicles (IoV), and the application of mass connectivity technologies, there is a mounting demand for ultra-high-rate, ultra-broadband communications, and low-latency communications. However, the transmission technology of existing antennas cannot satisfy this support well. The terahertz antenna with high bandwidth and high directional characteristics can better fulfil the communication needs of ultra-wideband, high speed, large-scale connection and low latency. Although the existing literature has already done a lot of research work on terahertz antenna design, there are still the disadvantages of complex structure, high fabrication difficulty and high price, as well as the disadvantages of a single operating frequency band and inferior directionality. In this paper, we design a multi-band, ultra-wideband rectangular internal slotted terahertz antenna. The antenna has the characteristics of simple structure, small size (16mm×8mm), simple fabrication (metal film coating) and cheap material (copper). In this paper, the simulation is performed at the operating frequency of 100GHz, and the results show that the antenna has the characteristics of multi-band, ultra-wideband, high gain and good directionality near the operating frequency. Simultaneously, this paper simulates the optimization of slot width.
