“…Multi-Band antenna MIMO also has a maximum gain of up to 4.1dBi in terms of performance, and the highest efficiency value is 71%, so it can be used in various electronic devices such as smartphones, tablets, and laptops. The antennas designed in [5,8,15,16,19,27] mainly the Sub-6G or 5G frequency band and are usually only applicable to a specific single electronic device. In addition, although the antennas proposed in [9,17] have the working frequency band of LTE and WLAN 2.4 GHz, none of these antenna designs can cover the frequency bands of Sub-6G and WiFi 7 at the same time, and in lower frequency bands such as LTE Both require the use of passive components to achieve.…”

This paper proposes a Multi-Band antenna suitable for LTE and 5G NR frequency bands. The Multi-Band antenna is designed on a 60 mm × 12.5 mm FR4 substrate without requiring passive components. The Multi-Band antenna uses a Coupled-Feed structure to reach the LTE900 frequency band, while the rest of the working frequency bands are implemented using a monopole antenna. Multi-Band antennas are implemented on electronic devices like smartphones, tablets, and laptops to form Multiple-Input Multiple-Output (MIMO) systems. Each Multi-Band antenna maintains consistency in measurement and simulation, with isolation below -10 dB, showcasing its robustness. The MIMO antenna system's envelope crosscorrelation remains below 0.5 across various devices, indicating stable performance. The above characteristics validate the Multi-Band antenna's applicability to diverse-sized portable electronics. Furthermore, Specific Absorption Rate (SAR), assessing radiation's impact on humans, is considered. Simulations of SAR for different MIMO antenna systems near the head, hand, or leg consistently meet safety standards, ensuring that MIMO antenna systems pose no radiation threat to human health.

INTRODUCTIONWith the continuous advancement of modern communication technology, fifth-generation (5G) communication technology has been born under the social demand for the internet and electronic communication equipment to meet the growing demand for communication transmission. In addition, the Multiple-Input Multiple-Output (MIMO) antenna system has the characteristics of increasing channel capacity and spectrum efficiency. As channel capacity increases, so does the transmission rate of the MIMO antenna system, allowing it to satisfy highthroughput and high-rate transmission requirements[1-5]. Therefore, MIMO antenna technology based on multi-antenna transmission has attracted a lot of attention [6][7][8][9][10].The reason is that MIMO antenna technology is to set multiple antennas in communicating electronic devices such as smartphones, tablets, and laptops. As the size of communication electronic equipment gradually decreases, it becomes difficult to design antennas in the limited area of communication electronic equipment. In the same time, it is difficult to maintain good isolation between antennas in a small space because the antennas can interfere with each other and affect signal transmission [11][12][13][14][15][16].This paper discusses some antenna design research in recent years and lists the following issues:1) In recent years, due to the popularity of 5G communication technology, there are many antenna designs used in Sub-6G and 5G NR frequency bands that are worthy of reference. In [17], the H-shaped monopole antenna for laptop was proposed. This antenna can be installed on the laptop without an additional ground plane and uses an ultra-thin size to reach the 5G NR band, which is a very suitable application for modern ultra-thin laptops. In [18], a 4×4 MIMO antenna system...

The paper presents a ground radiation antenna (GradiAnt) based triple-band MIMO antenna with wideband characteristics for Wi-Fi 6E applications. The GradiAnt is a novel antenna element with a series combination of inductor and capacitor in the feed loop, and dual-band characteristics have been achieved by controlling the impedance level of the antenna. By introducing a parasitic resonator within the feed loop of GradiAnt, triple-band characteristic is achieved, and significant bandwidth enhancement is realized, fully covering the Wi-Fi and Wi-Fi 6E operation bands. The resonator consists of a parasitic strip connected with the ground plane through an inductor. Two identical GradiAnts are symmetrically installed at the corners of the shorter edge of the 55 × 40 mm 2 sized ground plane for MIMO scenarios. A loop-type isolator is installed between the antenna elements to decouple the lower Wi-Fi band where the higher bands are self-isolated. The measured bands with reference to −6 dB are 2.36-2.63 GHz and 4.76-8 GHz. The isolation in the lower and higher bands is greater than 22 dB and 17.5 dB, respectively. The ECC is less than 0.03 in the lower band and 0.16 in the higher bands.

A distinctive low-profile 2 × 2 MIMO antenna system for Wi-Fi 7 applications is presented in this paper that is compact, easily manufactured and with excellent performance. Because of its compact size and good RF performance, the design can be placed in hidden locations for various applications such as the automotive field in the front side mirrors or front dashboard, and consumer products in laptops and internet wireless routers. The proposed design can cover the entire tri-bands of Wi-Fi 7 (2400-2495 MHz, 5150-5895 MHz, 5945-7125 MHz) using a loaded low-profile Planar Inverted-F Antenna (PIFA) with distinct dimensions and slots across its geometry. The element design and the MIMO system is simulated and a properly made prototype was fabricated to present the results in terms of reflection coefficients, current distribution, combined radiation patterns, passive isolation, ports efficiencies, and Envelope Correlation Coefficient (ECC). The design shows relatively good RF properties across the entire three bands, hence making it an attractive solution to be used for Wi-Fi 7 technology to satisfy the needs of larger omnidirectional coverage area, wider channel bandwidth, and better transmission rates with low interference.
