“…Various reconfigurable antennas with distinct switching have been tested; they include a novel switchable multiband frequency reconfigurable microstrip square slot antenna [10], and a novel bowtie frequency reconfigurable antenna [11]. A reconfigurable multiband bowtie slot antenna employs switchable pairs of slots [12]. A simple multiband reconfigurable antenna with dual pairs of PIN diodes [13] and a compact quad-band reconfigurable monopole antenna [14] have also been proposed.…”

A compact grounded asymmetric coplanar strip (GACS)-fed flexible multiband frequency reconfigurable antenna with two PIN diodes is proposed. The investigated antenna is backed by a flexible polyamide substrate with compact dimensions of 24 mm × 19 mm and a thickness of 1.53 mm. The investigated antenna structure contains a monopole patch that facilitates operation for wireless LAN applications, whereas inverted L-shaped and F-shaped monopoles facilitate operation for Bluetooth and 5G NR applications. The investigated antenna operates at 2.4, 3.8, and 5.6 GHz with measured impedance bandwidths of 5.8%, 6.3%, and 6.6%, respectively, over the three frequency bands, thus facilitating coverage for Bluetooth, 5G NR, and WLAN standards. The two PIN diodes are employed to tune the investigated antenna among four modes, including a single band mode (WLAN 5.5 GHz), two dual-band modes (5G NR 3.8/5.6 GHz, and Bluetooth 2.48/5.6 GHz), and one multiband mode with Bluetooth (2.4 GHz), 5G New Radio (NR) N77 band (3.8 GHz), and WLAN (5.6 GHz) modes. The investigated antenna radiates unidirectionally with a peak gain of 3.73 dBi at 5.6 GHz. Measurements are carried out on the human body to investigate the behaviour of the wearable antenna. The simulated SAR values are in a safe limit of 1.6 W/kg for 1 g of tissue, according to the FCC. Moreover, the investigated antenna shows extremely low vulnerability to degradation in performance as a result of bending effects concerning impedance matching with acceptable acquiescence between measurements and simulations.

In this paper, a Multiband-Frequency-Reconfigurable Antenna with a small compact size (20×35×1.6 mm 3) is presented. The designed antenna can work effectively under the following modes: two modes of single band and one mode with dual bands. The reconfigurability has been achieved accurately by switching (ON/OFF) the incorporated PINdiodes. The designed antenna is tested under the following applications; 3G, 4G AWS1 (1700-2100 MHz), Wireless-Area-Network (2.45 GHz and 5 GHz) and Worldwide Interoperability for Microwave Access (3.5 GHz). The designed antenna is fabricated as a C-shape monopole placed on the commercial FR-4 substrate. The antenna is simulated using the student version of the Computer Simulation Technology (CST-MWS). The three modes match the Reflection Coefficient (S11) <-10 dB and the efficiency >84%. The average gain ranged from 1.9 to 3 dBi. A prototype has been fabricated and measured. The comparison between the fabricated and simulated antenna results, such as S11, Efficiency, and gain, are illustrated. A good agreement between the results has been noticed which validates the design concepts.

“…Jalilvand et al presented and investigated antenna based on a new 3D microwave tomography approach [27]. Mansoul et al presented a compact antenna with 8 × 3 cm 2 space and obtained the enhanced peak gain performance of 4.5-5.8 dBi [28]. Wu et al [29] reported work on the slotted bowtie antenna with compact size (6 × 10 cm 2 ) and achieved a fair gain performance of 3.75 dBi, 3.56 dBi, and 3.93 dBi.…”

“…e authors in [35] investigated the antenna array with complex methodology and obtained the gain higher than 8 dBi. It is worthy noted that the results analyzed and explained in [25][26][27][28][29][30][31] the researchers have not paid attention to the radiation efficiency of the antennas; also, the suggested methods were complex. However, the proposed antenna presented in this paper employed an alternative method that outperforms the maximum gain, radiation efficiency, and compact dimensions in comparison with most of the previously reported work.…”

This paper presents a new design of a compact, high-gain coplanar waveguide-fed antenna and proposes a multielement approach to attain enhanced characteristics. The proposed method overcomes the simulation and geometrical complexity and achieves optimal performance features. The antenna prototype is carefully designed, and simulation results have been analyzed. The proposed antenna was fabricated on a new WangLing TP-2 laminate with dimensions (0.195λ × 0.163λ × 0.0052λ) at the lowest resonance of 9.78 GHz. The results have been tested and experimentally verified. The antenna model achieved excellent performance including a peak realized gain better than 9.0 dBi, optimal radiation efficiency better than 87.6% over the operating band, and a good relative bandwidth of 11.48% at 10 dB return loss. Symmetrical stable far-field radiation pattern in orthogonal planes and strong distribution of current are observed. Moreover, a comparative analysis with state-of-the-artwork is presented. The measured and simulation result shows a good agreement. The high-performance antenna results reveal that the proposed model is a good contender of military airborne, land, and naval radar applications.
