“…Many studies have been carried out on various antenna types to achieve a wide bandwidth along with high-performance parameters. The commonly employed techniques are the design of various Vivaldi antennas, spiral antennas, log-periodic antennas and disk-cone antennas [4][5][6][7]. However, these types of antennas suffer from a bigger dimension, which limits their use for compact size devices.…”

This paper presents the design and realization of a compact printed ultra-wideband (UWB) antenna with notching characteristics for compact devices using a genetic algorithm. The antenna is capable of mitigating an adjacent sub-band ranging from 3.75 to 4.875 GHz, mainly used by many applications and standards such as WiMAX, WLAN and sub-6-GHz. The notch band functionality is achieved by etching out two symmetrical slots from the pentagonal radiating element. The simulation and measured results demonstrate that the proposed antenna overperformed compared with state-of-the-art antennas in terms of compactness with an overall size of 20 mm×15 mm×0.508 mm. Moreover, the proposed design shows a large bandwidth in the UWB region with a fractional bandwidth of 180% with respect to the center frequency of 5.25 GHz. The antenna also presents omnidirectional radiations all over the operation band and a good return loss performance.

This paper presents a compact AMC structure used as a shielding element for a generic wearable RFID tag at UHF frequencies for on-body applications, with an overall footprint limited to an area of only 0.03 λ0 2 (41.4 mm  82.8 mm). Thanks to the isolation provided by the AMC planar structure, the tag antenna gain and reading range are increased of about one order of magnitude in comparison with the case of a conventional tag attached to the human body. The designed antenna is platform tolerant, with a very good robustness and isolation with respect to the human body, exhibiting a high reliability. The AMC structure is implemented on a thin, flexible and biocompatible high permittivity silicon-doped dielectric substrate, with apertures both in the substrate and in the ground plane to allow skin transpiration. Therefore, the presented device can be effectively used also as an epidermal antenna, allowing the "onskin" sampling of the most typical health parameters. The presented configuration has been designed using CST Studio Suite. A prototype has been fabricated and fully characterized, and measured results are in very good agreement with simulations.

This paper describes the design, fabrication, and test of a printed planar log-periodic dipole antenna to be used as a standard gain antenna in simple, low frequency, anechoic chamber far-field antenna measurements. The design procedure is size constrained by the photolithographic printing circuit fabrication process. Maximum gain and an input reflection coefficient below −10 dB are envisaged for the frequency range 0.5-2.5 GHz. The antenna is printed on a low cost FR4 substrate, and a careful analysis, with optimization of all the antenna physical parameters namely: number, length, spacing and width of the dipoles, width of the feed line traces, feed line termination, feed balun, and substrate shape, is carried out. The good agreement obtained between numerical simulation and experimental results provides validation of the proposed antenna configuration and design procedure.
