“…An X-band patch antenna with a coplanar waveguide (CPW) structure which can be directly connected to the antenna and transmit receiver modules without additional wiring is proposed. Therefore, when external factors are affected, unnecessary movement can be controlled and the deterioration of antenna performance can be reduced to a minimum [20]. Rectangular slot patches can also achieve impedance bandwidth by stacking cylinders with perforations and etching a rectangular slot on the ground side.…”

This paper proposes a simple and small-dimensioned antenna that can provide X band and Ku band for the low-earth-orbiting (LEO) satellite system in an Internet of vehicles system. The antenna is designed on the substrate Arlon DiClad 880. The antenna structure consists of an inverted triangle geometry and an inverted U-shaped slot. The dimensions of the antenna are 12.5 × 5 mm2, and the area of the substrate is 30 × 13 × 0.254 mm3. The antenna is easy to make, and the manufacturing cost is low. The measurement results of the reflection coefficient (lower than −10 dB) of the antenna show that the working frequency band can cover the X-band (10.87–12.76 GHz) and the Ku band (15.19–16.02 GHz). The measured and simulated results are fairly similar. The efficiency of the antenna in the X-band is about 50–80.8%. The efficiency of the antenna in the Ku-band is about 50–74%. The gains of the antennas are about 3.34–6.08 dBi and 3.50–4.65 dBi in the X-band and Ku band, respectively, and the highest gain is 6.08 dBi. The antenna design can realize the features of low cost and small dimensions in autonomous vehicles and vehicle networking communication system equipment and achieve good wireless transmission capabilities from vehicles to the base station in the IOV.

“…Due to the harsh operating environment of a military ship, the connection between the antenna part and the TRMs must be robust with regard to the external shocks. Therefore, an interface layer is employed between the antenna part and the TRMs, which prevents any unwanted movement of the feed-pin due to the external shocks as shown in Figure 1(d) [16], [17]. The geometric parameters are optimized using a genetic algorithm and the FEKO EM simulator [18], [19], and they are listed in Table 1.…”

In this paper, we propose an S/X-band shared-aperture array antenna with a mutual complementary design to improve the electromagnetic (EM) transparent characteristics. A unit-cell of the proposed antenna includes one dual-loop element for the S-band and 33 dual-loop elements for the X-band. To configure the shared-aperture structure in a limited space, the S-band element is stacked on top of the Xband elements. To solve the practical engineering problems of the shared-aperture antennas, novel design techniques such as using a mutual complementary structure, a coupling compensation array, an interface layer, and an antenna modularization are employed. To verify the antenna feasibility, the fabricated unit-cell extends into a 44 unit-cell array. The fractional bandwidth of the reflection coefficients for the proposed array are 14.7% and 15% in the S-and X-bands, respectively. In the S-band, as the steering direction of the main beam increases from 0 to 45, the maximum gain decreases from 14.6 dBi to 11.8 dBi. In the X-band under the same conditions, the maximum gain varies from 26.6 dBi to 25.3 dBi INDEX TERMS Array antennas, shared aperture antennas, radar, dual loop antennas, mutual complimentary design.

“…Although UWB technology offers numerous advantages, one challenge is to build an UWB antenna that is small, with appropriate impedance with good radiation stability and efficiency and a reduction of signal interference in the UWB frequency spectrum with achieve narrower bands [3]- [7].

The patch antenna with Ultra-Wide Band (UWB) characteristics is a promising candidate for wireless communication. It is a major research problem to mitigate electromagnetic interference (EMI) with narrowband technologies such as 5G lower band, Wi-MAX, WLAN and satellite band, which are all in the UWB region. This study describes a UWB antenna with variable band rejection that can be used to avoid interference with Wi-MAX and 5G lower band applications. The UWB characteristics of a simple rectangle patch antenna with a faulty ground structure has been designed for operational bandwidth (2.7–13) GHz. A novel method semicircular slot (SCS) at the radiation patch creates a band notched from (3.25–3.80) GHz and (3.4–4) GHz. Variable band rejection between (2.95–4.40) GHz can be achieved by adjusting the “Wa” values. When measured over the band rejection frequency, the return loss (S11) and VSWR values are very close to 0 dB and larger than 2. The simulated and measured results such as return loss, VSWR, 2-D polar pattern and gain have almost similar agreement. The design of the suggested antenna is simple, compact and efficient for Wi-MAX application, this is an ideal UWB antenna with the band notch characteristics.
