Dual-Band Antenna on 3D-Printed Substrate for 2.4/5.8 GHz ISM-Band Applications

Abstract

In this paper, we present a dual-band antenna working at 2.45 GHz and 5.8 GHz. The design is based on two radiating rectangular slots with one upper Split Ring Resonator (SRR) to enhance the radiation pattern at 5.8 GHz, one Complementary Split Ring Resonator (CSRR), and three Split Rings (SR) to improve the input reflection coefficient. The dual-band antenna covers the 2.45 GHz and 5.8 GHz Industrial, Scientific and Medical (ISM) bands. The total size of the proposed antenna is 31 × 70 × 70 mm3. The proposed antenna was manufactured and tested. The attained gain is better than 7.5 dBi, and 6.5 dBi at 2.4 GHz and 5.8 GHz, respectively. The measured gain and input reflection coefficient have good correlation with the simulated results, covering the ISM bands around 2.45 GHz and 5.8 GHz. The performance of the proposed antenna is remarkable and suitable for applications where the size is not a severe limitation, such as sensors, LPWAN/WLAN modules, health care devices, base stations, IoT, and control applications.

Three-Dimensional Printed Annular Ring Aperture-Fed Antenna for Telecommunication and Biomedical Applications

“…Moreover, 3D printing is a unique venue for RF circuits, promising especially novel antenna design for 5G telecommunications systems [7]. It can be employed to ease the implementation and realization process of a complex substrate of RF components [8][9][10][11][12][13][14][15][16][17]. However, some challenges, such as soldering, are associated with the 3D-printed substrate.…”

Metasurface loaded dual band antenna for high gain on- and off- body communication

“…Among various band spectrum used globally for variety of applications, the 2.45 GHz and 5.8 GHz frequency bands have become key players in a multitude of applications, including Wi-Fi, Bluetooth, and various industrial, scientific, and medical (ISM) devices as well as for their usage in IoT devices, radar systems, point-topoint communication along with wireless backhaul and wearables [12][13][14]. Moreover, since the beginning of present decade an exponential growth in number of communicating devices per person is observed due to increased usage of smart watches, fitness bands, cell phones and tablets [15].…”

Design of a Crossed Dielectric Resonator-Loaded, Dual-Band Dual-Polarized Differential Patch Antenna with Improved Port Isolation and Gain

“…In multi-band antenna designs, parasitic structures [4][5][6][7] and slots [8][9][10][11] are commonly used to generate multiple operation bands. For example, fan-shaped parasitic patches are introduced to circularly polarized patches [4], and additional resonant mode can be excited at a lower band with linearly polarized characteristics.…”

“…In [8] and [9], symmetric slots etching at the edges of radiating patches contribute to a higher resonant mode at the upper band. Except for the above designs, multi-band characteristics can also be obtained by loading shorting pins or stubs [11][12][13]. For example, a dual-band microstrip patch antenna is designed in [12] using four shorting pins and a slot, and the radiation gain reaches 10.2 and 10.0 dBi at the two bands.…”
