“…In addition to photonic electromagnetic wave sensing, this bowtie antenna has a various other potential applications, such as microwave radars, nano-antenna arrays, plasmonic sensing and Terahertz-wave detection [39]. Besides, this type of bowtie antennas can be fabricated by inkjet printing techniques in solid or contour forms [20,42] on flexible substrates [20,43], which is compatible with roll-to-roll manufacturing processes [44,45]. Furthermore, the gold material can be replaced by ITO or graphene, together with the transparent feature of the silica substrate, to potentially enable some 'invisible' integrated electronic and photonic devices [46].…”

“…In addition, the resonant frequency of a bowtie antenna can be designed and tuned by appropriately modifying and scaling the bowtie geometry, such as its arm length, flare angle, and feed gap width. This enables the bowtie antenna to have various applications over a wide frequency range, including extremeultraviolet light generation [2], optical antennas [3,16,5], Terahertz-wave optoelectronics [17], mid-infrared plasmonic antennas and sensors [8,18], microwave radar [7], wireless communications [4,19], flexible RF devices [20], complex electromagnetic structures [21], and photonic detection of freespace electromagnetic waves [22][23][24].…”

Abstract-The bowtie antenna is a topic of growing interest in recent years. In this paper, we design, fabricate, and characterize a modified gold bowtie antenna integrated on a transparent silica substrate. The bowtie antenna is designed with broad RF bandwidth to cover the X-band in the electromagnetic spectrum. We numerically investigate the antenna characteristics, specifically its resonant frequency and enhancement factor. Our designed bowtie antenna provides a strong broadband electric field enhancement in its feed gap. Taking advantage of the low-k silica substrate, high enhancement factor can be achieved without the unwanted reflection and scattering from the backside silicon handle which is the issue of using an SOI substrate. We simulate the dependence of resonance frequency on bowtie geometry, and verify the simulation results through experimental investigation, by fabricating different sets of bowtie antennas on silica substrates and then measuring their resonance frequencies. In addition, the farfield radiation pattern of the bowtie antenna is measured, and it shows dipole-like characteristics with large beam width. Such a broadband antenna will be useful for a myriad of applications, ranging from photonic electromagnetic wave sensing to wireless communications.

“…Therefore, the flexible antenna design topic attracts the attention of design and research engineers [10][11][12][13]. Accordingly, single planar designs of flexible bowtie antenna [10], dual-band antenna for WLAN applications [11], dual-band LCP antenna for RFID applications [12] and flexible monopole antenna [13] were recently performed. But the flexible antenna can be also imagined to be implemented on innovative systems as curved radar cross sections [14].…”

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.

“…In order to realize a multiband antenna, different techniques can be used, like associating monopoles [11], designing a fractal antenna [12] or a wideband antenna [13]. In this paper, we present a new design of dipolar multiband antenna.…”

Abstract-In this paper, a multiband flexible antenna is presented. This antenna was realized on a flexible substrate in order to realize a deployable system for a distress beacon. We used the concept of open-sleeve antenna to change a quadrupole mode into a dipole mode. The main radiating element of the antenna is a dual-band folded U-shaped antenna. The operating frequencies of this antenna are studied depending on the length of the parasitic elements. In order to understand the matching and the radiation patterns in far field of both antennas (U-shaped and open-sleeve), their magnetic behaviors in near field are studied in simulation and in measurement. The simulated and measured radiation patterns are also presented to check the study in near field.
