“…Antenna design has a considerable challenge to obtain a small size with high data rate handling capabilities due to the constantly growing data capacity needs and the trend towards miniaturization of wireless communication systems. Adopting multiple-input multiple-output (MIMO) antennas, which improves both spectrum utilization and data speeds, is a practical solution to this issue [2][3][4]. Techniques to reduce mutual coupling and enhance isolation in a MIMO antenna among the antenna elements are necessary for the effective design of a spatial diversity in a MIMO antenna.…”

A dual-band serrated microstrip MIMO antenna is proposed for 5th generation wireless applications in this article. Here, the designed MIMO antenna is a serrated basic microstrip patch antenna. The dual-band microstrip MIMO antenna is excited by utilising a 50 Ω transmission line. A full ground copper layer has been utilized in the design to attain a better isolation, whereas the fabricated antenna's isolation among the antenna elements is measured to be greater than −20 dB. The simulated −10 dB impedance bandwidth of 160 MHz (3.340-3.50 GHz) and 220 MHz (5.50-5.72 GHz) can cover 3.40-3.60 GHz and 5-5.7 GHz fifth generation bands. In addition, the measured ECCs are less than 0.0025 and 0.001 at the two resonant frequency bands and for the two MIMO antennas. The antenna diversity parameters covering ECC and DG were analyzed. The average gain for the single-element, dual-port and quad-port MIMO antennas is 3 dBi. These parameters make the serrated microstrip MIMO antenna also suitable for intelligent IOT devices operating in sub-6 GHz band.

“…Its characteristic is that the mode itself does not depend on the excitation, so the characteristics of the mode can be analyzed by studying the characteristics of the antenna itself in the absence of excitation, so as to determine the appropriate mode. Then, the required characteristic mode excitation of the antenna is carried out through the appropriate feeding mode to achieve the initial design objectives and performance indicators of the antenna [24][25][26][27][28][29][30][31][32][33][34].

In this paper, a WiFi-UWB multiband monopole antenna is designed, fabricated, and tested based on the characteristic mode theory, which mainly consists of an L-shaped metal, an "ok"-shaped metal radiator, and a T-shaped metal patch. The substrate dimensions are 40 × 43 × 1.6 mm 3 , featuring a rectangular ground plate at the substrate's bottom. The "ok"-shaped metal on the upper surface is composed of a metal ring and a curved finger-shaped metal. To improve impedance matching and broaden the bandwidth, strategic modifications are implemented. Specifically, a rectangular slot is introduced at the top of the L-shaped metal, and the T-shaped metal is rotated 90 • counterclockwise and positioned beneath the "ok"-shaped metal. The microstrip feed line, constructed from metal, incorporates a feed point. Simulation results indicate that the antenna effectively covers the frequency ranges of 2.30-2.50 GHz and 3.65-9.77 GHz. At the resonance point, the maximum return loss is below −40 dB, signifying superior directional radiation characteristics. The antenna design is characterized by a wide frequency band, simple structure, and holds significant practical value for multi-frequency communication.

This paper illustrates a single antenna structure that simultaneously satisfies the antenna requirement for 5G cellular and global navigation satellite systems (GNSS). The antenna has a linearly polarised omnidirectional radiation for the newly defined 5G sub‐6 GHz cellular bands in the 617–5000 MHz frequency range. In contrast, a right‐hand circular polarisation (RHCP) with a hemispherical radiation pattern at the GNSS L1 has a frequency range of 1559–1606 MHz. This multi‐function antenna would provide a simplified product design and better space utilisation, particularly suitable for flat antenna modules and automotive. The primary concept involves employing a planar inverted F antenna structure to generate radiation modes for cellular bands and incorporate U‐slot on the top plate to generate the GNSS radiation modes. The design methodology utilises the characteristic mode analysis tool to tune the desired radiation characteristic mode at the intended frequency range for each function. The antenna was fabricated, and the performance was evaluated on a 1‐m ground plane. The GNSS RHCP gain measures 5 dBc at boresight, with an axial ratio below 2 dB across the L1 bands, while the cellular gain maintains an excellent return loss and omnidirectional radiation pattern performance across the cellular bands.
