Design of Siw Based on Chip Slot Antenna for Terahertz Frequency

Abstract

This research presents an operation of on chip antenna at Terahertz frequency range (0.6–0.68 THz). The overall dimensions of antenna are 1000×1000×100μm. The design of metamaterial (MTM) based on chip antenna contained five stacked layers of polyimide and aluminum as ground and top substrates, radiation patches, ground plane and feed line. On the 50um top polyimide layer, four radiation patches are implemented which convey circular-shaped and the feed is given on the 50um base- polyimide layer by implementing square microstrip lines i.e., further connected to each other also, waveguide port is used to excite the antenna. A coupling square slot on the ground layer has sandwiched between bottoms to upper layers. Initialization of electromagnetic waves from bottom feed to top radiation patches has conducted through coupling square which executed on ground plane. To attain high performance parameters without expand antenna’s size, the MTM and SIW properties have been adjusted to the antenna construction by applying linear tapered slots on the patch upper surfaces and metallic vias all over the middle ground layer jointed upper and bottom substrate to each other. The slots act as series Left Hand (LH) capacitor and the vias represent as shunt LH inductors. The results show that the proposed antenna including compact size, large bandwidth on terahertz range, low profile, low cost, simple design, and easy to construct can be conceivably suitable for THz integrated circuits. The proposed results have achieved by CST Microwave Studio software.
