“…The radiation efficiency of each frequency band is higher than 10% and satisfies the design goal. Table 2 lists the performance comparison of the proposed antenna with previously proposed antennas in terms of system ground size and antenna size [25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43]. Three types of planar antennas were compared in Table 2, namely the tridimensional structure, single-sided planar antenna, and double-sided planar antenna.…”

Wireless Sensor Networks (WSNs) had been applied in Internet of Things (IoT) and in Industry 4.0. Since a WSN system contains multiple wireless sensor nodes, it is necessary to develop a low-power and multiband wireless communication system that satisfies the specifications of the Federal Communications Commission (FCC) and the Certification European (CE). In a WSN system, many devices are of very small size and can be slipped into a Universal Serial Bus (USB), which is capable of connecting to wireless systems and networks, as well as transferring data. These devices are widely known as USB dongles. This paper develops a planar USB dongle antenna for three frequency bands, namely 2.30–2.69 GHz, 3.40–3.70 GHz, and 5.15–5.85 GHz. This study proposes a novel antenna design that uses four loops to develop the multiband USB dongle. The first and second loops construct the low and intermediate frequency ranges. The third loop resonates the high frequency property, while the fourth loop is used to enhance the bandwidth. The performance and power consumption of the proposed multiband planar USB dongle antenna were significantly improved compared to existing multiband designs.

“…The coverage of the frequency bands is the first condition. The following designs support three frequency bands [28,30,31,33,34,35,36,37,39,40,41,42,43]. The next property to consider is the antenna size, where that in [43] and the proposed design in this study are the smallest, as listed in Table 2.…”

Initially, we construct the metamolecule from its constituent meta-atoms, namely, a split ring resonator (SRR) and a complementary SRR (CSRR) which have characteristic oscillator frequencies in the microwave frequency band (especially in the X-band). Next, an one-dimensional metamolecule waveguide is created from an array of the CSRR-SRR meta-molecules. The CSRR is the negative image of the SRR therefore this waveguide is called Complementary Metamolecule Waveguide (CM-WG). Using electromagnetic (EM) simulations, we study the operation frequency bands of the CM-WG changing the polarization of the incident EM wave as well as its unit cell dimension. In continue, we develop an electrical transmission line model, we precisely calculate the electric and magnetic coupling coefficients between the metamolecules and verify the results of the EM simulations. We conclude, from the electromagnetic simulations and the analytical considerations, that the polarization of the incident EM wave and the distance between the metamolecules affect the bandwidth of the frequency bands as well as the properties of the propagation.

“…However, again the total size of the antenna is large. In [6,7], triple band monopole antennas with multi-stub loading and pairs of SRRs are designed respectively, but they use costly substrate, and the size becomes the constraint. The shortcomings of the above antennas are overcome by inverted-F antennas.…”

In this paper a novel branch-line printed inverted-F antenna (IFA) loaded with a rectangular complementary split-ring resonator (CSRR) is proposed, designed, and experimentally studied. The proposed antenna shows four operating frequencies and can be used for various cellular and wireless applications (900 MHz/3.5 GHz/4.2 GHz/5.5 GHz). The antenna is compact in size having dimensions 0.059λ 0 × 0.053λ 0 × 0.002λ 0 at the lowest resonance frequency. Each of the bands is independently tunable and shows circular polarisation (CP) in the WLAN band with linear polarization (LP) in the other three bands. The axial ratio (AR) bandwidth is 1.82% in WLAN band. The simulated and fabricated results are reported in terms of S-parameters and radiation pattern. The prototype of the antenna has been fabricated and measured using VNA and simulation done in ANSYS HFSS.
