“…The method to realize the broadband property of antenna are investigated. Using ferrites [3] or loading resistance can broaden the bandwidth while maintaining a small size but the cost is the reduction of the efficiencies. Other alternative methods of broadening the bandwidth are explored in recent years.…”

Antennas with broadband radiation and small-size are highly required in wireless communication system. The trade-off relation between bandwidth and size became a difficulty when it comes to miniaturized antenna design. A method of realizing antenna miniaturization and bandwidth enhancement at the same time is needed. Monopole antennas are the most common used one in the devices of Internet of Things, Internet of Vehicles, and wireless access points, et al. In this paper, a wideband low-profile top-loaded patch monopole antenna based on surface current engineering is proposed. The topology combines a center-fed circular patch with inductive vias. The patch is designed with patterns, which consists of four concentric annular rings and some strips in radial direction. In this way, three resonances are generated, and the pattern is optimized to bring three resonances close to each other. The number of the strips is specially designed to bring three resonances close to each other. By loading the inductive vias on the outermost rings, connecting to the ground, the resonance at low frequencies can be enhanced, as a consequence of the optimized impedance matching. The field distribution is analyzed to verify the operation principle. A prototype is fabricated, and the measured results agree well with the simulated ones. The relative −10 dB bandwidth is 69% and the omnidirectional radiation pattern is stable in the operating band. The antenna achieves a rather wideband radiation while maintaining a low profile. The method of antenna miniaturization and bandwidth enhancement based on surface current engineering paves the way for antenna design in low-profile ultra-wideband applications.

In this paper, a wearable ultra‐wideband (UWB) monopole antenna with a compact structure and low profile is presented for wireless body area networks, wireless local area networks, and UWB applications. The antenna is composed of three triangular radiators on the basis of the mono‐cone antenna. By the methods of reactive and slot loading, the dimension of the antenna can be greatly reduced. The overall height of the antenna is 0.06 λ0 at its lowest operating frequency. The radiated structure of the proposed antenna with the dimension of 31 × 31 × 9 mm3, which operates in 2.3 to 12.6 GHz, is fabricated and the measurement results are in good agreement with the simulated ones. Moreover, the influence of the human tissue on the antenna was evaluated, and stable performance can be obtained on the human tissue under different bending conditions. The specific absorption rate values are lower than the limitation set by the European Telecommunications Standards Institute, which indicates that the antenna is suitable for wearable applications.

This paper presents the novel design and fabrication of a square shaped array antenna for transmission in the higher X band and Ku-band. The influence of the constituent square’s size factor over the signal quality with the squares positioned in various array configurations is recorded and reported using a discretized design approach. The design was fabricated and tested to meet the needed standards after being optimized using the antenna simulator software. A novel DC shorting approach has been devised and reported to improve antenna performance. Major antenna performance parameters are being observed and found in accord with the literature.
