“…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].…”

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.

“…The dipole is designed by using a double-sided printed antenna etched on both sides of a dielectric substrate. Bow-tie technique is used to increase the bandwidth of the antenna [5]. So the radiator is actually a balanced radiator consisting of two triangular arms in the two different sides of a substrate.…”

Abstract-A new radiation pattern reconfigurable antenna is designed and fabricated. The antenna is able to radiate in four orthogonal directions in the azimuth plane and sweep the whole azimuth. The radiation pattern reconfigurability is obtained using the passband and stopband characteristics of EBG surfaces which are used to form EBG panels to surround the feeding dipole centered in the structure. Switching between passband and stopband is implemented using active elements in the structure.

“…Distance between intersection of the triangular in the bow-tie geometry is studied. Detailed optimization of the structure is performed to ensure satisfaction of requirements [14,15]. Geometric modifications as well as introduction of RF MEMS switches have also been reported to increase bandwidth [16].…”

Two different tri-band microstrip patch antenna designs are presented. Antennas are designed and simulated using the commercial simulation Sonnet Suites [(Sonnet Software, version: 12.56 www.sonnetsoftware.com (2009)] and simulated results are compared against measurements in detail. Target application of the first design is radar systems in IEEE 802.11, wireless communications in wireless local area network and worldwide interoperability for microwave access bands. The second tri-resonance antenna is designed to operate in the 9-13 GHz band and comparisons between simulations and measurements are presented. Results show three resonance frequencies at which design presented herein achieves return loss better than 30 dB with the maximum 10 dB return loss bandwidth of 4%. Resonance frequencies are 9.52, 10.66, and 12.60 GHz, which meets the design specification of covering the X-band. A detailed parametric study of the geometry, dielectric thickness, and dielectric constant is also provided. V C 2011 Wiley Periodicals, Inc. Int J RF and Microwave CAE 22:75-84, 2012.
