This work presents a purpose to accelerate the design process of mmWaves filters for 5G applications. To aim this objective, this work makes use of a technique of an artificial neural network called the multilayer perceptron. The model has 4 outputs and 6 inputs, where 2 outputs have a strong correlation and the other two have a weak correlation. By using 1000 samples, the model achieves an accuracy value of 0.927 for the outputs with strong correlation, but despite the good result, the predicted model still needs improvement, since |S11| had a not-so-nice performance.

“…Typically, antenna is the largest part of a wireless system, and previously it was not feasible to integrate it on a chip. However, due to the push towards millimeter-wave spectrum, antenna sizes have dropped to the order of millimeters and thus become compatible with the typical chip dimensions [4][5][6]. On the other hand, silicon (Si) based semiconductor technologies, such as a Complementary Metal Oxide Semiconductor (CMOS) process, have come a long way and thus high-frequency circuits and antennas can be realized on a single chip in a compact fashion [7].…”

System-on-Chip (SoC) has become an attractive solution to achieve highly integrated wireless systems. However, the Antenna-on-Chip (AoC) suffers from poor radiation due to the lossy silicon substrate in standard CMOS processes. Artificial Magnetic Conductors (AMC) with the ground plane above the silicon can enhance the radiation, however, fitting the AMC completely in the thin stack-up (~10-15 μm) is extremely challenging, particularly for frequencies below 100 GHz. In this paper, Metallic Posts (MP) and Embedded Guiding Structures (EGS) have been investigated to reduce the AMC thickness by employing the available vias and metal layers in the stack-up. An in-house CMOS-compatible process has been used to realize the AoC, where typical low-conductivity adhesion layers have been avoided to reduce the undesired losses by using the surface roughness in a unique fashion. With MP and EGS approaches, AMC thickness can be reduced by 33% and 41% respectively. The AMC with EGS fits within an oxide of a thickness of 16 μm. A monopole antenna, backed by this AMC, demonstrates a gain of 5.85 dBi and radiation efficiency of 57% at 94 GHz, bettering the gain and radiation efficiency by 9.15 dB and 42% respectively as compared to the case without AMC.

“…Distributed-element circuits approach can produce a similar behavior using λ g /4 resonators, where λ g = λ/ √ ϵ r . Even so, the resonators measure only a few millimeters (R L ∼ 0.5 mm for the alumina substrate), requiring advanced manufacturing techniques, like CMOS or BiCMOS [3].…”

This work presents a third-order interdigital bandpass Butterworth filter designed to operate in the ISM band from 57 to 66 GHz. The project adopted an aluminum oxide (alumina) substrate, copper microstrip transmission lines and a coplanar waveguide (CPW) interface. We performed electromagnetic analysis in Ansys EM using the Finite Element Method (FEM). The filter presented return loss greater than 10 dB and insertion loss greater than 4.47 dB from 57.04 GHz to 65.45 GHz. We will fabricate the device using the Metallic-Nanowire-Membrane technology.
