“…Unlike a multiband antenna, which resonates at multiple bands with low bandwidth, broadband antenna resonates around the center frequency and covers multiple frequencies with broad bandwidth. To achieve broad bandwidth, a slot structure in patch and ground is used, which excites the antenna's multiple resonance modes [16][17][18][19][20].…”

This article introduces a planar monopole antenna specially designed for NB-IoT module devices. The preferred choice for Internet of Things (IoT) technology is the Narrow-Band Internet of Things (NB-IoT) due to its extensive coverage and low power consumption. NB-IoT is specifically designed for IoT applications. A circular patch antenna with dimensions of 30 mm × 60 mm is fabricated, which is specifically tailored for the NB-IoT module. The antenna dimensions are meticulously chosen to ensure compatibility with the device module, considering the NB-IoT B1 (2100) and B3 (1800) frequency bands. Among various patch shapes, the circular design is preferred for its advantages over hexagon and square patches. The desired antenna configuration combines a square-slotted patch with a monopole ground plane, and it offers several advantages in terms of design simplicity, compact size, and characteristics such as broad bandwidth, acceptable gain, and high radiation efficiency. The design process employs HFSS Software and utilizes an FR4 substrate of 1.6 mm thickness. Operating at resonance frequencies of 2.1 GHz and 1.8 GHz, the antenna covers a broad frequency spectrum of 1100 MHz (1.5 to 2.6 GHz) with a fractional bandwidth of 53.65%. The suggested antenna achieves a peak gain of 3.3 dB and maximum radiation efficiency of 96% within its operating band. It exhibits an omnidirectional radiation pattern, meeting the specific requirements of NB-IoT technologies. Experimental measurements of the fabricated antenna validate the results achieved from the simulated data.

A microstrip patch antenna for Global Positioning System (GPS) application is presented in this study. It has a rectangular shape with two notched slots. The notched slots are introduced to improve the adaptation between the microstrip line and the antenna. The antenna was designed and simulated by CST using FR-4 material as the substrate with relative permittivity of 4.3. The proposed microstrip antenna is designed to operate in the GPS band frequency from 1.555 GHz to 1.595 GHz. The performance analysis of the proposed antennas has been carried out in terms of return loss (dB), gain (dB), and VSWR.

A miniaturized 2 x 1 multiple-input multiple-output (MIMO) antenna is presented in this paper. The designed antenna contains two circular patches with Complimentary Split-Ring Resonator (CSRR) that are etched in the ground which has a profound effect on antenna size reduction. It also helps in the reduction of isolation between two antennas. The maximum isolation between the two antennas is -84.62 dB at 2.8 GHz. The size of an antenna becomes more compact i.e., 40 x 20 x 1.6 mm3 after incorporating CSRR. The maximum gain of the designed antenna is 5.8 dBi at 4.3 GHz and the minimum reflection coefficient is -35.15 dB at 1.63 GHz. The operating band of an antenna is wide from 1.3 GHz to 4.3 GHz which covers Bluetooth, WiMax, and LTE applications. The proposed antenna is useful for various wireless applications.
