“…Moreover, the merging of numerous wireless systems into a single electronic device has boosted the need for multi-band, lowprofile, planar, low-cost, and miniature antennas [1][2][3]. The band spectrum allocated for Bluetooth (2.4 GHz), Industrial Scientific and Medical (ISM-2.4 GHz), LTE (Long-Term Evolution), the 5G sub-6 GHz spectrum (3.5 GHz), Wireless Local Area Network (WLAN), and 2.45 GHz and 5.8 GHz Radio Frequency Identification (RFID) channels are all popular frequency bands lying inside the frequency band ranging from 2-7 GHz [4][5][6][7][8][9]. The simple remedy to the problem is to devise a wide-band antenna covering the complete band spectrum.…”

This article describes the design of a tri-band antenna that operates at 2.45 GHz (ISM band), 3.5 GHz (5G sub-6-GHz band), and 5.8 GHz (WLAN band). The antenna design is inspired by a conventional quarter-wave monopole which is fed using a coplanar waveguide feed. Initially, the radiator is loaded with an inverted L-shaped stub to attain broadband across the band spectrum of 2.4 GHz. Then, a pair of two open-ended stubs are etched to achieve a higher frequency band of 5.8 GHz. Hereafter, another open-ended stub is loaded to the right end of the radiating structure, which results in the generation of the Sub-6 GHz 5G (3.5 GHz) band. Finally, the antenna is optimized using parametric analysis to improve the impedance matching across all bands. The proposed antenna offers a tri-band operational mode having frequency ranges from 2. GHz. The reported gains of the proposed antenna at respective frequencies are 2 dBi, 2.1 dBi, and 2.5 dBi having an omnidirectional stable radiation pattern. The antenna prototype is created on a small 20 × 16 × 1.6 mm 3 board, and measured to validate the results. Furthermore, the performance of the antenna is compared with the state-of-the-art works to demonstrate its key advantages over similar designs. ISM band, WLAN band, INDEX TERMS

“…Because it can operate digitally and provide low-power communications, the PIFA structure is a viable choice for sub-GHz range applications. Folded dipole approaches and meandering techniques are used to reduce size [23][24][25], and meander line antennas outperform PIFA in terms of bandwidth and radiation efciency [26,27]. In some literature, the metamaterial concept is also used to reduce the size of an antenna, increase the bandwidth of an antenna, and improve the radiation of an antenna [6,28].…”

This research article designs and develops a planar small-size antenna design for smart Internet of Things (IoT) communication with long-range technology (LoRa). The proposed system is best suited for transceiver systems in this automation and sensing era. In the proposed antenna, the ground, the radiating element, and the stub feed are designed on the same side of the substrate, keeping in mind that it can print the LoRa module. The design consists of a meandered monopole, a dipole structure as a ground, and a stub feed. A different design approach is employed to get an optimized result. The antenna is made up of a rectangular feed stub to which a connecting wire is attached. The overall dimension of the antenna is 55 m × 55 m × 1.6 mm. To verify the proposed design, an antenna was fabricated and measured, which covers the LoRa frequency band at 868 MHz, providing a sufficient bandwidth of 10 MHz and a gain of more than 0.5 dB in the operating band. A designed antenna is implemented for sensor data communication with the LoRa module device and device interface Arduino platform. The antenna is connected as a transmitter and receiver one by one to verify its performance with machine-to-machine communication using the LoRa module. The size, bandwidth, and radiation efficiency of this antenna are better than the antennas in the literature. The designed antenna is successfully implemented with LoRa connectivity and communicates the data up to 8 km in line-of-sight communication, more than 1 km in urban environments, and approximately 250 m of connectivity in building areas.

“…This implies that antennas operating from sub-6 GHz to mm-waves are required for IoT communication. Various dedicated antennas for their applications in the IoT at sub-6 GHz and mm-wave bands have been widely studied in the literature [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. These antennas operate either at sub-6 GHz [5][6][7][8][9][10][11][12][13] or mm-Wave bands [14][15][16][17][18][19][20][21].…”

The complete coverage of the operating frequency bands from microwave bands to millimeter (mm-wave) is required for the realization of the fifth-generation (5G) internet-of-thing (IoT) systems. Here, we present a multi-band antenna operating at the microwave (2.5/3.5/5.5/7.5 GHz) and mm-wave bands (23 -31 GHz), and its 12-port MIMO configuration with pattern diversity affording 360° coverage for 5G IoT applications. The multi-band characteristics are obtained by adding well-designed quarterwavelength stubs. The antenna operates at the important frequency bands from 2.37 -2.65 GHz, 3.25 -3.85 GHz, 5.0 -6.1 GHz, and 7.15 -8.5 GHz (|S11| < -10 dB), while it resonates from 23 -31 GHz at the mm-wave band with the desired radiation characteristics. Moreover, the antenna has more than 95% radiation efficiency and a stable gain (> 2.5 dBi at microwave band and 6.5 dBi at mm-wave bands) characteristics. In addition, the single-element antenna is translated to design a 2 × 2 MIMO antenna. This MIMO unit is further utilized in the formation of 2 × 4 and the proposed 3 × 4 (12-port) MIMO configurations to achieve spectral and pattern diversity. Considering the unique three-dimensional arrangement of the antenna elements, the 12port MIMO system is the only one of its kind that offers the codesign of microwave and mm-wave antenna, good isolation, and pattern diversity, providing complete 360-degrees space coverage in elevation and azimuth planes. The proposed antenna module is suitable for 5G IoT, especially in an indoor scenario for smart houses, offices, and vehicle-to-everything communications.
