“…By adding the simulated efficiency and the measured impedance bandwidth of 0.77 and 1.27, respectively, the EBIV index is ~32.85. Thus, the proposed monopole antenna has a higher figure of merit of EBIV index compared to the reported monopole antennas in [15–23]. The comparison of the EBIV of different recently reported monopole antennas in [15–23] are given in Table 1.…”

“…Utilizing the proposed technique of combining new radiating patch with a new arc-shaped strip, microstrip feed line, and notched ground plane, the antenna achieves a 127% wide impedance bandwidth, ranging from 4.9 to 22.1GHz (at VSWR ≤ 2). The proposed antenna is compact compared to the designs reported in [15–23], which are useful at VSWR ≤ 2. However, they cease to be useful when VSWR is below 1.5, as it does not cover the impedance bandwidth at that range.…”

In this paper, a new compact wideband monopole antenna is presented for wireless communication applications. This antenna comprises of a new radiating patch, a new arc-shaped strip, microstrip feed line, and a notched ground plane. The proposed radiating patch is combined with a rectangular and semi-circular patch and is integrated with a partial ground plane to provide a wide impedance bandwidth. The new arc-shaped strip between the radiating patch and microstrip feed line creates an extra surface on the patch, which helps further widen the bandwidth. Inserting one step notch on the ground plane further enhances the bandwidth. The antenna has a compact size of 16×20×1.6mm3. The measured result indicated that the antenna achieves a 127% bandwidth at VSWR≤2, ranging from 4.9GHz to 22.1GHz. Stable radiation patterns with acceptable gain are achieved. Also, a measured bandwidth of 107.7% at VSWR≤1.5 (5.1-17GHz) is obtained, which is suitable for UWB outdoor propagation. This antenna is compatible with a good number of wireless standards, including UWB band, Wimax 5.4 GHz band, MVDDS (12.2–12.7GHz), and close range radar and satellite communication in the X-band (8-12GHz), and Ku band (12-18GHz).

“…Transparent film based antennas with ultrawide bandwidth have been less adequately investigated, and this may be due to the difficulty of device fabrication, lossy nature and low efficiency of transparent materials [4,9]. Monopole antennas have received a lot of attention due to their good characteristics, such as ultrawide bandwidth, simple structure, and ease of fabrication [10][11][12][13][14][15][16][17][18]. In this work, we present a new type of ITO and glass based optically transparent monopole antenna with an extremely large fractional bandwidth.…”

An on-glass optically transparent monopole antenna with ultrawide bandwidth is presented in this work, and the proposed antenna is of ring shape and coplanar waveguide fed structure. Optically transparent indium tin oxide (ITO) thin film with a thickness of ~160 nm is used as the conductive layer, which is sputtered on an optically transparent glass substrate. An impedance bandwidth of 6 GHz from 1 to 7 GHz is achieved, with a return loss lower than −10 dB, meaning a fractional bandwidth of 150%. The proposed antenna exhibits reasonable radiations of omni-directionality in the H plane and bi-directionality in the E plane. Like other transparent antennas discussed in literature, the antenna gain is relatively low (−4 dBi at 5 GHz). In order to optimize the antenna performance, multi-film approach is proposed to reduce its sheet resistance, and the result shows that the antenna gain at 4 GHz can be improved from −8 dBi to 5 dBi when optimizing the sheet resistance from 10 Ω/sq to 0.01 Ω/sq. The designed antenna possesses a high optical transparency, which makes it easy to integrate to the surface of windows or display panels, and it can be applied for solar energy harvesting and many other ultra-wideband applications, with little chance of detection.
