Abstract-This paper presents a compact, low-profile, wearable dual-band antenna operating in the Wireless WLAN band of 5.15 ∼ 5.25 GHz and 5.72 ∼ 5.83 GHz. The proposed antenna is composed of a planar monopole and underneath three by three array arrangement of Jerusalem Cross (JC) structure metasurface. The simulated results show that the integrated antenna express 4.09% and 4.14% impendence bandwidths, increased gain up to 7.9 dB and 8.2 dB, front to back (FB) ratio achieved to 20 dB and 18 dB at the two frequencies, respectively. The measured results agree well with simulations. In addition, the metasurface not only is equivalent to a ground plane for isolation, but also acts as the main radiator, which enables a great reduction in the specific absorption rate (SAR). Furthermore, because of a compact solution, the proposed integrated antenna can be a promising device for various wearable systems.

“…Moreover, textile based antennas are prone to discontinuities in substrate materials in addition to the textile nature of fluid absorption. A flexible, compact antenna system intended for telemedicine applications was proposed by (Raad et al, 2012). The design is based on an M shaped printed monopole antenna operating in the Industrial, Scientific and Medical (ISM) 2.45 GHz band integrated with a miniaturized slotted Jerusalem Cross (JC) HIS ground plane.…”

“…By observing the changes of the corresponding frequency band of return loss of different length dipoles antennas versus inphase reflection, the effect of curvature on the reflection phase is determined. Raad et al (2012) proposed a systematic approach to characterize the performance of a flexible HIS when subjected to different extents of bending is proposed. The performance of an array of squarepatch based HIS under various bending extents was investigated as a benchmark.…”

Recent years have witnessed a great deal of interest from both scientific and academic communities in the field of flexible electronic systems. Most flexible electronic systems require the integration of flexible antennas operating in specific frequency bands to provide wireless connectivity which is highly demanded by today's network oriented society. On the other hand, High Impedance Surfaces have become very popular in the design of contemporary antenna and micro-wave devices due to their wide range of applications derived from their unique electromagnetic properties which significantly enhance the performance of antennas and RF systems. Accordingly, the integration of HIS structures within flexible wireless systems is very beneficial in this growing field of research. In this paper, a systematic review of flexible HIS structures reported in the literature is conducted, which provides the reader with a thorough description and a complete list of state of the art designs intended for flexible wireless systems.

Abstract-Recently, the RF/microwave electronic technology evolved with the consideration of plastic and organic substrates. Such a technology offers two-folded benefits: in one side for lowering the fabrication cost and in another side for the possibility to bend electronic devices. Such a technology is particularly interesting for the implementation of antenna system. This paper is dealing with the design of flexible microstrip 1×2 antenna array. Theoretical approach on the typically symmetrical 1×2 antenna array is proposed. The design methodology of microstrip antenna combined with 1 : 2 T-power divider (T-PWD) is described. Based on the transmission line theory, the S-parameter model of the antenna system with non-standard reference load is established. Then, the microstrip antenna passive system is theoretical analysed in function of the physical dimensions of the designed structure. The feasibility of the flexible antenna passive system is investigated with the proof-of-concept (POC) designed on Kapton substrate. The POC prototype consisted of microstrip 1 × 2 antenna array is designed to operate at about 5.8 GHz. Comparisons between the full wave simulated and measured return losses were performed. Then, simulated radiation pattern highlights the efficiency of the fabricated prototype of passive antenna array.
