“…Ultra-Wideband (UWB) technology uses nanosecond non-sine-wave narrow pulse to transmit data, which has high data transmission rate, so it can be used in antenna design and manufacture. UWB antenna has a wide bandwidth coverage, suitable for signal transmission of different frequencies, and small size and high efficiency, so it has been widely used [1][2][3][4][5][6][7][8][9][10][11]. A dual-mode UWB antenna is proposed in [5], which consists of monopole and dipole of the same structure and is excited by a coplanar waveguide.…”

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.

“…By combining these two technologies，bluetooth can be used when m-level location with the indoor positioning system, and UWB can be used when making cm-level precision positioning with the indoor positioning system. So a Bluetooth and UWB-integrated indoor positioning system with both advantages can be obtained [1][2][3][4].…”

Aiming at the antenna performance requirements of Bluetooth and UWB indoor positioning system, an octagon monopole dual-frequency indoor positioning beacon antenna is made. The antenna can operate in both UWB and Bluetooth communication bands. The antenna performance is improved by grooving the antenna and adding metal strips. The use of curved and gradual structure feeders also makes the antenna get better bandwidth performance.

“…I n addition to reducing electromagnetic interference from narrowband communication systems, ultra-wideband (UWB) antennas with notching properties can increase the antenna's bandwidth to a certain degree [1]. In the design of a notch UWB antenna, traditional antenna simulation tools, such as highfrequency structure simulation (HFSS), can accurately calculate various performances of the antenna.…”

To address the stressful and time-consuming problem with the current notched antenna modelling optimization tools, an improved deep multilayer perceptron (DMLP) neural network framework is designed. The method introduces an attention mechanism (Attn) layer to improve the interpretability of the model, uses the leaky ReLU activation function to prevent the gradient from vanishing, and optimizes the structure of the DMLP model using an improved particle swarm algorithm (PSO) to improve the model prediction accuracy. Then, the notch structure geometric parameters of the designed double-notch ultra-wideband (UWB) antenna serve as input to predict the return loss S11 of the antenna. The experimental results show that the method reduces the root mean square error of prediction for S11 by 73.01% compared to the traditional MLP and 64.14% compared to the unimproved DMLP, which provides a solution for modelling notched UWB antennas and helps to optimize the design of this type of antenna.
