“…And the flatter the gain curve, the better the receiving characteristic of antennas. Therefore, an important parameter ∆G=Gain max -Gain min [12] is defined to describe the variation of gain values. To achieve stable gain, an ultra-wideband CP crossed-dipole antenna was designed in [13].…”

A broadband Circularly Polarized (CP) cross-dipole antenna with the merit of stable gain is proposed. The designed antenna consists of crossed dipoles, parasitic patches, reflectors, and vertical parasitic plates. By adding parasitic patches and parasitic plates, the circular polarization performance of the antenna is significantly improved. Furthermore, the gain value becomes stable in the entire operating frequency band by modifying the structure of the parasitic plates. The final dimension of the presented antenna is 0.76λ0 X 0.76λ0 X 0.28λ0 (λ0 is the wavelength at the center frequency point in the circularly polarized working frequency band). The measured results depict that the Impedance Bandwidth (IBW) is 80.8% (2.03GHz~4.78GHz) and the Axial Ratio Bandwidth(ARBW) is 68.5% (2.35GHz~4.8GHz). Stable gain values, ranging from 6dBic to 7.5dBic, are obtained in the working frequency band, and the average gain can reach 7dBic.

In this work, an ultra-wideband double slot Vivaldi antenna (DSVA) loaded with a novel wideband nonresonant metasurface is proposed to enhance the gain. The semi-elliptical slots are etched on both sides of the ground plane of the DSVA to improve the current distribution. In addition, the nonresonant metasurface composed of WiFi-shaped unit cells could maintain a stable high refractive index in the operating bandwidth of 1−18 GHz, which could bend the outgoing wave to the end-fire direction. Both the original antenna and the proposed antenna are simulated, fabricated, and characterized. The measured results are in good accordance with the simulated ones. The return losses of both antennas are less than −10 dB in the frequency range of 2−13.4 GHz, while the gain of the proposed antenna is improved from 13.6 to 16.3 dBi with a maximum gain enhancement of 3.1 dB.

“…Printed antennas have been extensively used in wireless communication systems. They are simple in structure, small, easy to fabricate, economical to produce, exhibit reasonable gain & have reliable radiation performance, generally for a wide bandwidth [8][9][10]. Implementation of multiband printed antennas in smart home devices is always preferred in order to support 5G, LTE, Wi-Fi, Bluetooth, and Zigbee technol-ogies simultaneously [11,12].…”

A compact, dual-band 1 × 2 coupled monopole printed antenna array design is proposed in this paper for indoor IoT-based smart home devices and sensors. With an overall dimension of 30 × 70 × 1.5 mm 3 , the presented design is operational at two frequency bands ranging from 3.6 to 4.3 GHz and from 5.6 to 6.6 GHz with stable impedance matching. The coupled planar monopole configuration ensures a consistent radiation performance over a wide bandwidth. To verify the practical implementation of the antenna on an IoT platform's device, the effects of dielectric height and ground plane variation on impedance matching over a wide frequency of operation are also discussed.
