In recent years, deep distributed neural networks (DDNNs) and neural networks (NN) have excelled in an extensive list of applications. For example, deep convolutional neural networks (DCNNs) are constantly gaining new features in various tasks in computer vision. At the same time, the number of end devices, including Internet of Things (IoT) devices has increased prominently. These devices are attractive targets for machine learning applications because they are often directly connected to sensors. For example (cameras, microphones, and gyroscopes) that record large amounts of input data in a stream mode. This study presents the design of a DDNN with end devices, edges, and clouds that spans computer hierarchies. The idea presented is considered one of the new ideas because it depends on two layers to distinguish, namely the convolutional layer and the pooling layer. The main objective behind using these two layers in one proposal is to provide and obtain the best results. Finally, we discovered that the proposed technique produced the best results in terms of accuracy and cost, with the precision of the definition reaching 99 % and the cost being quite affordable at 25. As a result, we conclude that these results are far superior to those achieved by the researchers in their ideas provided in previous recent literature.

In this paper, a compact two-shape slot microstrip antenna is proposed for global positioning system (GPS) satellite application. The proposed antenna is designed with FR 4 substrate with a height of 1.6 mm, a dielectric constant εr of 4.3 within a compact size 56 x 56 mm2 area. The design parameters are optimized to achieve good performance. At the optimum setting of design parameters, this antenna shows good characteristics to cover L1 band 1,575.42 MHz, ± 12 MHz frequency which is used for GPS satellites. At the 1,572 MHz resonance frequency, this antenna achieves a minimum return loss of -30 dB covering a frequency bandwidth of 50 MHz (1,550 MHz – 1,600 MHz) at -10 dB reference level which ensures 100% bandwidth coverage of the L1 band. Besides, the proposed antenna achieved a maximum gain of 8.3 dBi and a beam width of 1010 at -3 dB point. In terms of other performance, such as voltage standing wave ratio (VSWR), directivity, radiation pattern, the proposed antenna shows good performance for the application of GPS satellites.

“…The peak gain reaches to 12.02 dB and it offers limited bandwidth of 1GHz at single operating band centered at 28 GHz. In [12], a compact 29  49  1.6 mm 3 multiband MIMO antenna is presented using a rectangular zigzag shaped slots and it achieves an isolation of greater than 30 dB. In [13], a proximity coupled MIMO antenna operates at 28 GHz for 5G mm-wave application with a compact size of 8.0  8.0 mm 2 with improved mutual coupling of less than -24 dB.…”

In this paper, a novel compact dual-wide band multiple input multiple output (MIMO) antenna system with a better performance for 5G communications systems at mm-wave frequencies (28/38 GHz) is presented. Firstly, a single element was designed and detailed to resonate at mm-wave band frequencies (28/38 GHz). The basic antenna is a simple circular patch that resonates at 38 GHz. In order to generate the second operating frequency of the proposed antenna, two rectangular inverted L-shaped slots are introduced (Ant II). Furthermore, to improve the impedance matching at desired frequencies, a circular slot is introduced on the radiating element (Ant III). Two inverted F-shaped and rectangular DGS are inserted on the ground plane to improve the operating bandwidth of the antenna (proposed single element antenna). A low-cost substrate FR4epoxy having a relative constant 4.4, loss tangent of 0.02 and thickness of 0.74 mm is used in this design. The simulated result shows the proposed single antenna has the better performances. The single antenna has a compact size of 7  6.8  0.74 mm 3 . Furthermore, the two single elements are transformed into 2-port MIMO configuration for mm-wave 5G MIMO applications. To achieve the improved isolation characteristic of the MIMO antenna, a rectangular DGS is introduced in the center of the ground plane. The result indicates that this antenna shows a reflection coefficient under -10 dB over a range from 26.82 GHz to 38.16 GHz with bandwidth of 11.34 GHz (F.B.W 34.90 %). The gain of the antenna is found more than 5 dB in the whole operating band width. The MIMO antenna is also characterized by good isolation ranging from 19 to 56 dB. Additionally, the MIMO antenna has a compact size of 15.5  6.8  0.74 mm 3 . Due to these superior results, the proposed MIMO antenna could be a potential candidate for MIMO 5G mm-wave applications.
