“…With the rapid development of wireless communication, modern communication systems require higher operating frequencies and more frequency bands [1]. Microstrip patch antenna (MPA) is widely used in wireless communications, satellite positioning, and other fields because of the characteristics of small size, low profile, low cost, and easy integration [2] [3]. Whereas it still exists the limits of low gain, narrow bandwidth, and single frequency in the design of traditional antenna [4].…”

This study proposes a Taiji-shaped microstrip patch antenna without affecting its size and design complexity. The radiation patch adopts a Taiji-like shape design, and the traditional Chinese Bagua-shaped parasitic element is loaded on the periphery of the radiation patch on the surface of the dielectric substrate to optimize the impedance matching further and improve the gain. The software HFSS15.0 is used to simulate the antenna and compare the results. The results show that the antenna achieves dual-band characteristics at 2.45GHz and 5.04GHz, has an impedance bandwidth of 110MHz and 250MHz, and has a positive gain of 7.13dB. The proposed antenna is suitable for the field of wireless communication.

“…Port isolation is a critical factor in evaluating the performance of dual-polarized antennas, as it determines the degree of independence between the orthogonal polarizations [ 1 ]. To improve port isolation, various techniques [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ] have been proposed in recent years. For example, a single-layer, dual-port, and dual-mode antenna with enhanced port isolation is proposed in [ 2 ].…”

“…In [ 3 ], the port isolation is improved for dual-polarized stepped-impedance slot antenna by using shorting pins. C-shaped structures and square rings are designed to enhance the isolation between stacked microstrip patch antenna arrays [ 4 ]. In [ 5 , 6 ], dielectric superstrates and Defected Ground Structure (DGS) are utilized to improve the E-plane and H-plane isolation.…”

In this study, we present a novel dual-polarized patch antenna that exhibits high isolation and two in-band transmission zeros (TZs). The design consists of a suspended metal patch, two feeding probes connected to an internal neutralization line (I-NL), and a T-shaped decoupling network (T-DN). The I-NL is responsible for generating the first TZ, and its decoupling principles are explained through an equivalent circuit model. Rigorous design formulas are also derived to aid in the construction of the feeding structure. The T-DN realizes the second TZ, resulting in further improvement of the decoupling bandwidth. Simulation and experimental results show that the proposed antenna has a wide operating bandwidth (2.5–2.7 GHz), high port isolation (>30 dB), and excellent efficiency (>85%).

“…Frequency selective surface wall has been used to decouple two dielectric resonator antennas by 30 dB throughout the working 57-63 GHz band. A Cshaped structure is used to reduce coupling between two patch antenna elements by 20 dB [26]. A metallic post is incorporated between two MIMO crossed dipoles to reduce mutual coupling by a maximum of 13 dB within the band [27].…”

A novel customized π-shaped split-ring resonator metasurface arranged in two configurations is presented to decouple 1×2 and 1×4 Millimeter-Wave (MMW) Magneto-Electric (ME) Dipole in the H-Plane with 1.6 mm (0.32λ at 60 GHz) inter-element spacing. The metamaterial unit cell is first designed to inhibit the propagation of coupled surface waves within the bandwidth of interest. A 5×2 arrangement of this unit cell is carefully positioned on the top and bottom of the superstrate with 1 mm spacing (0.2λ at 60 GHz) between the antenna and the superstrate. In the 1×2 array, a maximum measured mutual coupling reduction of 53 dB is observed within the 52-66 GHz bandwidth (23.7%). To further demonstrate the uniqueness of the metasurface, an 11×2 configuration of this unit cell is arranged as a superstrate for the 1×4 ME-dipoles. A maximum measured mutual coupling reduction of 40 dB is achieved without a considerable effect on the radiation characteristics. Parametric analysis is performed to confirm the uniqueness of this new decoupling structure. The proposed antenna exhibits measured high total efficiency (> 89%), high gain (> 8 dB), low envelope correlation coefficient (<0.0003), and very good radiation characteristics throughout the entire bandwidth. The fabricated prototype antenna is measured to validate the simulation results. The proposed antenna is a good recommendation for V-band millimeter-wave MIMO applications like radar research.INDEX TERMS Millimeter-wave magneto-electric dipole, multiple-input-multiple-output (MIMO), split ring resonator.
