This paper presents a triple band proximity fed 2 × 1 array antenna with defected ground plane. The proposed antenna configuration is composed of two radiating elements, and both radiating elements are made of a pattern similar to the first iteration level David fractal geometry. The proposed David fractal 2 × 1 array antenna is designed and simulated on an FR-4 substrate of thickness 1.6 mm and dielectric constant 4.3 by using the CST Microwave Studio simulation tool. In order to improve the radiation characteristics of the antenna, an H-shaped defect is etched in the ground plane. The antenna is fabricated and tested. The experimental data show good agreements with simulation results. The fabricated triple band fractal 2 × 1 array antenna resonates at 2.527 GHz, 3.329 GHz, and 3.742 GHz having bandwidths of 303 MHz, 99 MHz, and 102 MHz, respectively. The proposed fractal array antenna can be used in mobile applications such as Wi-Fi, WLAN, Bluetooth, and Wi-Max.

“…In addition, fractal structures were implemented to provide wideband characteristics (Rahim et al, 2019). Multi-band technique for wireless applications can be achieved by incorporating slots over structures (Zavosh & Aberle, 1996), fractal geometries (Baliarda, 1998), stubs at various locations (Ali & Biradar, 2017), multi-layered structures (Firdausi & Alaydrus, 2016), reconfigurable structures (Sung, 2014), aperture coupling feed, feeding techniques (Casula et al, 2016), insertion of parasitic elements, electronically reconfiguring the antenna using microelectronic switches (Parchin et al, 2020) or by making defected ground structures (DGS). Multi-band antenna is reported in slotted rectangular patch antenna for wireless applications (Malik & Singh 2019).…”

This paper proposes a novel compact, single structure, multi-band antenna along with tested results for wireless local area networks (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX) applications. In this work, modified complementary split-ring resonators (CSRR) were incorporated in the ground layer of the patch to achieve permeable bands to accommodate multi-resonance frequencies in a single device. The proposed antenna design supported the upgraded performance and led to desirable size reduction. Open stubs were incorporated at the edges of the triangle batch to get the improved reflection coefficient responses. It resulted in specific band spectra of 2.4 / 3.4 / 5.1 / 5.8GHz for WLAN/WiMAX applications. For constructive antenna design, CST microwave studio simulation software was utilized. S11 parameter was observed as -24dB at 2.4GHZ, -32dB at 3.4GHz. -15dB at 5.1GHz and -22dB at 5.8GHz bands. Field patterns of each band were observed. The parametric study of the arrangement and positioning of the CSRR unit cell was examined. Excellent consistency between the experimental and simulated results revealed the capability of the projected structure to perform with improved gain.

“…An inkjet printed triple band antenna realized on resin coated paper substrate with overall dimensions of 35 × 40 mm 2 is proposed in [16]. The work in [17] presents a proximity coupled-fed microstrip flexible antenna with overall geometry of 40 × 40 mm 2 and dual band operation. In [18] a flexible antenna for Rogers RT/Duroid 5880 with thickness of 0.127 mm have been reported but it is not multiband.…”

This work presents a compact, quad-band planar antenna intended for assimilation into flexible and conformal devices. The CPW-fed semicircular shaped prototype with rake-shaped slots is designed, realized and characterized experimentally. The frequency bands covered by the proposed radiator are centered at 2.5, 3.7, 5.5 and 8 GHz with measured impedance bandwidths of 16%, 13.5%, 11.8% and 14.63%, respectively. The proposed antenna is thus enabled to support WLAN, ISM, Bluetooth, WiMAX, LTE and X-band applications. The antenna exhibits a significant gain. The radiation characteristics of the proposed radiator are measured in concave and convex bent shapes at various radii to analyze its flexibility. Performance of the antenna remains almost unaffected in the bent situation. Measurements demonstrate good coherence with simulations. The compactness and good performance of the design both in bent and unbent conditions proves it to be the better contender for future multiband conformal wireless applications.
