A Compact Triple-Band UWB Inverted Triangular Antenna with Dual-Notch Band Characteristics Using SSRR Metamaterial Structure for Use in Next-Generation Wireless Systems

Abstract

A compact triple-band operation ultra-wideband (UWB) antenna with dual-notch band characteristics is presented in this paper. By inserting three metamaterial (MTM) square split-ring resonators (MTM-SSRRs) and a triangular slot on the radiating patch, the antenna develops measured dual-band rejection at 4.17–5.33 GHz and 6.5–8.9 GHz in the UWB frequency range (3–12 GHz). The proposed antenna offers three frequency bands of operation in the UWB range, which are between 3–4.17 GHz (~1.2 GHz bandwidth), 5.33–6.5 GHz (~1.17 GHz bandwidth), and 8.9–12 GHz (~3.1 GHz bandwidth), respectively. The higher resonating frequency band can be tuned/controlled by varying the width of the triangle slot, while the medium operational band can be controlled by adjusting the width of the SSRR slot. Initially, the simulated S-parameter response, 2D and 3D radiation patterns, gain, and surface current distribution of the proposed UWB inverted triangular antenna has been studied using epoxy glass FR4 substrate having parameters εr = 4.3, h = 1.6 mm, and tan δ = 0.025, respectively. In order to validate the simulation results, the proposed UWB antenna with dual-notch band characteristics is finally fabricated and measured. The fabricated antenna’s return-loss and far-field measurements show good agreement with the simulated results. The proposed antenna achieved the measured gain of 2.3 dBi, 4.9 dBi, and 5.2 dBi at 3.5 GHz, 6.1 GHz, and 9.25 GHz, respectively. Additionally, an in-depth comparative study is performed to analyze the performance of the proposed antenna with existing designs available in the literature. The results show that the proposed antenna is an excellent candidate for fifth-generation (5G) mobile base-stations, next-generation WiFi-6E indoor distributed antenna systems (IDAS), as well as C-band and X-band applications.

An Electronically Reconfigurable Highly Selective Stop-Band Ultra-Wideband Antenna Applying Electromagnetic Bandgaps and Positive-Intrinsic-Negative Diodes

“…But adding filters makes the antenna size large, complex, and costly. Therefore, researchers have offered various methods that have been employed, including carving slots into the radiating element, incorporating electromagnetic bandgap (EBG) structures, and utilizing various split-ring resonators (SRR) for energy absorption [6][7][8][9][10]. By applying these techniques, single-and multi-notch-band antenna designs have been proposed in academia [11][12][13][14][15].…”

Design of a Monopole Antenna for WiFi-UWB Based on Characteristic Mode Theory

“…Ultra-Wideband (UWB) technology uses nanosecond non-sine-wave narrow pulse to transmit data, which has high data transmission rate, so it can be used in antenna design and manufacture. UWB antenna has a wide bandwidth coverage, suitable for signal transmission of different frequencies, and small size and high efficiency, so it has been widely used [1][2][3][4][5][6][7][8][9][10][11]. A dual-mode UWB antenna is proposed in [5], which consists of monopole and dipole of the same structure and is excited by a coplanar waveguide.…”
