Abstract
In this paper, a novel high-gain multi-layer antenna is designed for use in terahertz communication systems. The frequency range covered by this antenna is 8-13 THz. To improve the antenna's gain, a proposed rectangular metasurface structure environment has been used. To strengthen and connect the layers, several plastic bases have been used, which do not have a destructive effect on the antenna's radiation pattern. The use of the proposed rectangular metasurface structure medium has increased the gain by more than 10.5 dB compared to the conventional antenna.
Highlights
The antenna is one of the most important components in designing telecommunication systems to transmit electromagnetic waves or information between transmitters and receivers [1]
Aperture antenna, horns, and microstrip antennas are among the famous antenna types [2]
Methods of improving the performance of microstrip antennas include the design of array structure [3], the use of special materials such as graphene [4], the employ of metamaterials, metasurfaces, and electromagnetic bandgaps (EBG) [5,6,7], substrate integrated waveguide (SIW) [8], ridge gap waveguide (RGW) [9] technologies
Summary
The antenna is one of the most important components in designing telecommunication systems to transmit electromagnetic waves or information between transmitters and receivers [1]. Due to the use of metasurface structures in the central frequency of 5.6 GHz, the gain is more than 9 dBi. the performance of this antenna is good, but the large size is its most important drawback. The interesting thing is that very little research has been done to improve the performance of microstrip antennas at terahertz frequencies using metasurfaces. This is one of the most important contributions and is our motivation for the design of this antenna introduced in this paper. A high-gain multi-layer microstrip antenna using rectangular metasurface structure (RMS) at 8-13 THz for application in terahertz communication systems is proposed. To better prove the designs procedure, several optimizations as the parametric reports have been done with the mentioned simulators
