“…To improve service, IEEE 802.11 ac provides premium service for high-speed Wi-Fi on the 5 GHz frequency [12]. Another method to improve Wi-Fi performance is to upgrade the existing antenna with a microstrip antenna [13], [14]. TOPSIS and VIKOR algorithms were investigated in the Wi-Fi radio spectrum to address handoff failures [15].…”

At present, the need for data traffic is experiencing tremendous growth. The growth of smartphones technology offers new applications. On the other hand, the growth in cellular network access infrastructure has not been able to keep up with the increasing demand for data package services. For this reason, Wi-Fi offloading is needed, namely cellular users, using Wi-Fi access for their data needs. In 2016, global data communication traffic growth reached 63%. Many researchers have proposed the adaptive wireless fidelity (Wi-Fi) offloading (AAWO) algorithm to transfer data on heterogeneous networks. In this study, the proposed adaptive incentive scheme is classified, to obtain an adaptive scheme based on cost, energy, service quality, and others. From the survey results shown, there is no proposed adaptive algorithm based on the quality of experience (QoE). This provides an opportunity for further research where the Wi-Fi offloading scheme uses the perspective user or user experient options. In addition, open research uses artificial intelligence and machine learning methods as adaptive methods.

“…In order to reduce the dimensions of the designed resonator, the DMS technique [12][13][14] is employed to minimize the circuit size by etching slots in the microstrip line which disturbs the current distribution. As shown in figure 6, a slot DMS is integrated into the microstrip line of…”

This paper proposes a new design of a reconfigurable bandpass filter based on an interdigital capacitor and varactor diode for wireless and mobile applications. The designed reconfigurable bandpass filter has been implemented on an RT 6010 substrate with a relative dielectric constant of 10.2, thickness of 1.27 mm, and loss tangent of 0.0023. In order to reduce the filter size, the defected microstrip structure (DMS) is used due to its easy design, high compactness, high quality factor and easy integration with other RF devices. The suggested reconfigurable filter has a simple structure with a very attractive compact size of 4.7 × 8.4 mm2, low insertion loss than -1 dB, and tuning range (2–2.6 GHz).

A compact dual-band bandpass filter based on the substrate integrates suspended line platform is proposed in this letter. The design is implemented using low-cost FR-4 material, while the loss can be reduced by 3D metal connections with substrate cutout. 0.97 dB/1.6 dB improvement of insertion loss is achieved and verified at 3.45 GHz/4.9 GHz. By paralleling quarter wavelength step impedance resonators with different operating frequencies, two paths formed between source and load. Both bandwidth and location of transmission zeros can be adjusted independently. Two stubs are added working not only as feed structure but also as a stop band resonator, which can provide 20 dB out-of-band suppression up to 4.4f0. The obtained performances are good enough to compare with the state of art, though very low-cost FR-4 materials are used.
