“…A dual frequency-band is developed and achieved for UHF and SHF RFID applications [15]. Another prototype planar antenna with multi frequency bands is proposed in [16]- [20], which can cover 0.9 GHz, 2.4 GHz and 5.8 GHz frequency bands. Multi frequency-band monopole printed antennas can be achieved by using a stub tuning, slot techniques and a parasitic structure with a different shape [21], [22].…”

This research presents the development and conception of a new compact grounded coplanar waveguide fed slotted rectangular planar antenna with a multi-frequency band for <a name="_Hlk94076774"></a>radio frequency identification data (RFID) reader applications which is based on the antenna mono-band frequency to use for a various applications RFID to support a different operating range. The optimized of the final prototype designing operates a multiple frequency bands ranging from 0.7-1.1 GHz, 2.2-2.5 GHz and 5.4-6 GHz for 0.9/2.4 GHz and 5.8 GHz RFID operation bands which is adapted from ultra-high frequency band (0.9 GHz) to microwave frequency band (2.4-5.8 GHz) RFID systems. This antenna is implemented and printed on a FR4 substrate with a size of 30×50×1.6 mm3. The novel prototype includes of a radiator rectangular patch with a symmetrical slot and a U-slot with I-stub on ground plan. The principles parameters of the antenna have been studied optimized and miniaturized by using a two simulators CST Microwave Studio and advanced design system (ADS) to validate the simulation results before the planar antenna realization. The final structure is achieved and validated of the results measurement. Experimental results show that the proposed antenna with a small size has good and stable radiation and thus promising for a various RFID applications.

“…A planar monopole antenna with added L-and U-shaped monopoles was presented in [12] to provide four operating bands: 858-931 MHz, 1.571-2.845 GHz, 3.42-4.42 GHz, and 5.26-6.32 GHz. In [15], a monopole reader antenna for RFID portable devices was developed to cover three frequency bands: 902-928 MHz, 2.4-2.48 GHz, and 5.725-5.875 GHz. However, the size of the antenna is too large for the miniaturization of the terminal devices.…”

A compact coplanar waveguide-fed monopole antenna is presented in this paper. The proposed antenna is composed of three monopole branches. In order to achieve the miniaturization, the longest branch was bent. The antenna is printed on an FR4 dielectric substrate, having a compact size of 0.144λ0 × 0.105λ0 × 0.003λ0 at its lowest resonant frequency of 900 MHz. The multiband antenna covers five frequency bands: 820–990 MHz, 1.87–2.08 GHz, 2.37–2.93 GHz, 3.98–4.27 GHz, and 5.47–8.9 GHz, which covers the entire radio frequency identification bands (860–960 MHz, 2.4–2.48 GHz, and 5.725–5.875 GHz), Global System for Mobile Communications (GSM) bands (890–960 MHz and 1.850–1.990 GHz), WLAN bands (2.4–2.484 GHz and 5.725–5.825 GHz), WiMAX band (2.5–2.69 GHz), X-band satellite communication systems (7.25–7.75 GHz and 7.9–8.4 GHz), and sub 6 GHz in 5G mobile communication system (3.3–4.2 GHz and 4.4–5.0 GHz). Also, the antenna has good radiation characteristics in the operating band, which is nearly omnidirectional. Both the simulated and experimental results are presented and compared and a good agreement is established. The proposed antenna operates in five frequency bands with high gain and good radiation characteristics, which make it a suitable candidate in terminal devices with multiple communication standards.

“…Due to the limited space for these applications, designing a multiband antenna having satisfactory performance is a challenging task. Miniaturized antennas with multiband characteristic for mobile wireless applications, such as internet of things [1][2][3][4], wireless sensor networks [5], wearable devices [6,7], RFID portable devices [8][9][10][11][12], and implantable biomedical systems [13,14], have become urgent requirements. Over the past decade, various methods and optimization techniques have been introduced for multiband or wideband antenna design.…”

This paper presents a novel design methodology for the design and optimization of a miniaturized multiband microstrip patch antenna (MPA) for wireless communication systems. Two design steps are used to do that. In the first step, an initial antenna is designed by a trial and error approach to operate nearly in the desired frequency bands, but the level of impedance matching (s 11 < −10 dB) for one or more bands is unsatisfactory, or some bands are uncovered by the antenna. The second design step is used after that to achieve optimized antenna by applying an optimization algorithm to effectively fine-tune the impedance matching of the initial deigned antenna to closely satisfy all the desired frequency bands. As an illustrative example, the proposed optimization methodology is used for designing a miniaturized multiband MPA suitable for operating at five different frequency bands, 915 MHz (RFID band), 1850 MHz (GSM band), (ISM-Industrial, Scientific, Medical), 2.45 and 5.8 GHz, and 3.5 GHz (WiMAX band). The proposed MPA used here is composed of two patch structures printed on both sides of an FR4 substrate occupying an overall size of just 28 × 28 mm 2. The final optimized antenna is fabricated, and its simulated and measured results are coinciding with each other validating the design principle. Moreover, simulation antenna performance parameters, surface current distribution, realized peak gain, and efficiency besides the radiation patterns at the desired frequency bands are obtained using CST MWS.
