“…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.

“…Initially and recently also some researchers have suggested wideband monopole patch antenna for UWB applications using different shapes and techniques. [2][3][4][5][6]. However, this range is interfered by several unlicensed ranges (like WiMAX, C-band, WLAN, X-band etc) which introduced an interference with UWB and degrade the overall operations.…”

Present work illustrate CPW fed apertured monopole patch antenna having multiple interfering bands filtering capabilities. The proposed antenna contains three complementary improved inverted U-shaped slots on the radiating patch to filter out interfering signals namely WiMAX (3.3 to 3.6 GHz), C-band now extended for 5G application (3.7 GHz to 4.2 GHz) and WLAN (5.15 to 5.85 GHz) (combined lower 5.15–5.35 GHz and upper 5.725–5.825 GHz, WLAN). The ground plane is surrounded over the radiator with few modifications on the top corner to enhance impedance matching and hence to obtain optimized overall bandwidth. The projected antenna is made up on substrate of FR-4 (er=4.4) with height of 1.6mm and all the characteristics has been studied with VNA in anechoic chamber environment. The simulated and physically verified responses are in very close treaty to each other. Filtering capability is cross verified with ADS systematic software and lumped-equivalent circuit model also proposed with respective values of all the elements used. Time domain and current distribution analysis has also been undertaken to strengthen the functioning of antenna.

In this article, a detailed performance analysis of a novel flexible monopole antenna with a %141.46 impedance bandwidth in the 2.4-14 GHz UWB range is present. The antenna is fabricated on a flexible Kapton substrate with compact geometry for different technology applications under different bending conditions. The airbrush printed technique was preferred due to its advantages such as easy production, conductivity control, and no loss of surface waves. The antenna has dimensions of 82x57x0.125 mm3 and is fed by a coplanar waveguide transmission line. All necessary antenna simulations are performed using CST. According to the positions of identical antennas face to face, face to side, side to side, time-domain analysis is performed for the impact response analysis. The transmission coefficient characteristics (S21) and the group delay are measured for various bending conditions. Time and frequency domain analyzes show that the proposed UWB antenna has the much-needed stable performance in UWB antenna. The proposed UWB antenna has good performance over the operating spectrum for a flat and bending configuration.
