摘要

In this work, a cradle wave ring-shape multiband novel design terahertz antenna employed and excited with a microstrip feed is proposed. The regular deca-shape ring evolutions develop the final proposed novel antenna design. The proposed deca-shape ring antenna demonstrates good performance at 1 THz–5 THz with a good reflection loss, which is less than − 10 dB. The complete geometrical dimensions of the antenna design are 120 × 200 × 10 μm³. The MIMO parameters are interpreted, and good performance is achieved. The resonating bands of the antenna are 1.66 THz, 2.37 THz, 2.90 THz, 3.07 THz, and 3.56 THz with reflection coefficients of − 31.7 dB, − 19.3 dB, − 16.4 dB, − 18.6 dB, and − 28.5 dB. The antenna featuring dual ports with a novel geometry demonstrates good MIMO performance. The cradle wave ring shape, unique design, and uniform spacing, as well as the radiation characteristics, make the antenna a good candidate for emerging 5G applications. The proposed antenna is composed of two ports and exhibits satisfactory MIMO performance. With its special cradle wave ring design geometry, it can provide very efficient performance such as radiation properties at Port 1 and Port 2. The gain achieved across the operating frequencies is greater than 7 dBi. The proposed novel design is intended for and suitable for 5G, wearable electronics, military communication, and ultrafast short-range wireless high-speed high-resolution radar applications.
