This paper presents wireless integrated compact, lightweight and portable printed circuit board (PCB) device of air quality monitoring system (AQMS). The system is fabricated in double-sided three PCBs to observe real-time data of CO2, CO, NO2 and weather parameters. For the convenience of 3D stacking, the PCB design is built on three boards so that it consumes minimum area. The volume of the entire board is found 110 mm × 80 mm × 24 mm. Strategy of power reduction has been adopted in the design. To reduce power consumption, switching technique is applied to the electronic sensors. This technique is controlled by the use of demultiplexer device. This low power switching technique enhances the battery life of the AQMS structure has been enhanced. Experimental results show that with the chosen batery bank, average power is 1.0588992 Watt during runtime operation of the device. Thus, AQMS runs in safe mode for 33.75 hours continuously using a fully charged power bank. Electrostatic discharge (ESD) protection has been introduced in the PCB to prevent the circuit damage from high voltage during data transmission. The system is capable of being powered by natural resources such as the solar system, which is installed to charge lithium-ion battery. Moreover, the physical weight of the fabricated device is 172gm excluding the weight of the package.

“…Moreover, in addition to the EMI effect cancellation, the enormous sleeping potential of DGS need to be explored by the EMC, signal integrity (SI), RF and microwave design researchers. Under such a circumstance, we can point out that the DGS enables also to enhance the signal integrity (SI) performances [10], [11] and suppression of microwave device harmonics [12]. In more general review, the DGS constitutes one of promising design solution and miniaturization minimizing the EMIs of various microwave passive circuits [12]- [22].…”

A bandpass negative group delay (NGD) passive circuit based on defect ground structure (DGS) and substrate integrated waveguide (SIW)-matched is developed in the paper. The NGD DGS topology is originally built with notched cells associated with self-matched substrate waveguide elements. The DGS design method is introduced as a function of the geometrical notched and SIW via elements. Then, parametric analyses based on full wave 3-D electromagnetic S-parameter simulations were considered to investigate the influence of DGS physical size effects. The design method feasibility study is validated with fully distributed microstrip circuit prototype. Significant bandpass NGD function performances were validated with 3-D simulations and measurements with −1.69 ns negative group delay value around 2 GHz center frequency over 33.7 MHz NGD bandwidth. Insertion loss is 4.37 dB, and reflection loss reaches 41.5 dB.

“…Several techniques have been reported in the literature to reduce mutual coupling. The isolation techniques include the insertion of slots or ground irregularities [4][5][6][7], uniplanar, mushroom type, and various shapes of electromagnetic bandgap structures (EBG) [8][9][10][11][12], split-ring resonators (SRRs) [13][14][15], metamaterials [16] and meander line resonators [17][18][19]. Not only these techniques but several antenna configurations such as superstrate configurations of photonic bandgap structures [20] and orientations have been reported to be useful in minimizing coupling effects.…”

This paper presents an isolation enhancement of two closely packed multiple-input multiple-output (MIMO) antenna system using a modified U-shaped resonator. The modified U-shaped resonator is placed between two closely packed radiating elements resonating at 5.4 GHz with an edge to edge separation distance of 5.82 mm (λ∘/10). Through careful adjustment of parametric modelling, the isolation level of −23 dB among the densely packed elements is achieved. The coupling behaviour of the MIMO elements is analysed by accurately designing the equivalent circuit model in each step. The antenna performance is realized in the presence and absence of decoupling structure, and the results shows negligible effects on the antenna performance apart from mutual coupling. The simple assembly of the proposed modified U-shaped isolating structure makes it useful for several linked applications. The proposed decoupling structure is compact in nature, suppress the undesirable coupling generated by surface wave and nearby fields, and is easy to fabricate.
