In mixed-signal circuits, the return currents of sensitive analog and noisy digital signals must be carefully isolated in order to protect the integrity of the analog signals. To address this issue, a common approach is to utilize slots on the reference plane between digital and analog circuits. However, the slots so created cause the discontinuity in the return current path for a signal passing over these slots which causes unintentional radiation and results in unwanted electromagnetic interference (EMI). In this regard, we propose the planar interdigital slot structures for use in reference planes of multilayer PCBs in order to provide a low impedance path for return current. The interdigital structure alleviates the return current path discontinuity and hence reduces the unintentional radiation. In addition to this, a relationship between radiated emission and transmission response is obtained, allowing the designer to tune the slot parameters to minimize radiation at the signal frequency. PCBs with different size planar interdigital slot structures are simulated in Ansys HFSS and is found that the longer digit length corresponds to better EMI reduction, especially at higher frequencies.

Behavioral model is an effective tool to design nonlinear radio frequency and microwave circuits. Using accurate behavioral model, engineers can greatly reduce circuit development time by eliminating the need to build expensive and time-consuming hardware prototypes. At present, noise modeling of low noise amplifiers (LNA) mainly focuses on equivalent model, while relatively little research has been done on behavioral model. Therefore, this paper will study the behavioral model of the the LNA. It includes the theoretical derivation of the noise parameter testing process of the LNA, the extraction and the verification of the behavioral model of the LNA in simulation.

This paper presents the design and implementation of concurrent multiband impedance matching networks (MBIMNs) for low noise amplifiers (LNAs). The designed MBIMNs were implemented using microstrip lines on FR-4 and Roger’s 5880 substrates. The designed dual band IMN (DBIMN) operates at 900 MHz and 2.0 GHz. The |S11| for DBIMN circuit are -20dB and-23dB at 900 MHz and 2.0 GHz, respectively. For the designed triband IMN (TBIMN), the three bands are centered at 900 MHz, 2.4 GHz and 3.2 GHz and the measured |S11| are -44.6dB, -14.7dB and -33.9 dB, respectively. The proposed technique can be implemented to design MBIMNs at other frequencies.

To better solve the accuracy degradation of human motion recognition due to low signal-to-clutter-plus-noise ratio (SCNR) and low resolution of through-the-wall radar (TWR) imaging, a triple-link fusion decision human motion recognition method for through-the-wall radar is proposed in this paper. This method combines the physical information, visual local information and visual global information in imaging. Specifically, the idea of complementarity of three weak models, including empirical modal decomposition (EMD) algorithm based on statistic signal detection, visual gradient-level based kernel method and visual regionalized macro-level based shuffle attention improved residual neural network (SA-Inception-ResNet) algorithm are introduced in the method, and the Dempster-Shafer (D-S) synthesis theory is used to achieve decision level fusion recognition. The final results are inferred by an adaptive boosting method on the trained weak models and the fused strong model. Experiments are carried out to demonstrate that the accuracy of the algorithm exceeds 99.54%, while the prediction performance and robustness are significantly improved compared with previous methods.

In this paper, a semi-active limiter in the 6~18GHz frequency band is designed. The limiter adopts a two-stage cascade design. The front-stage limiter uses a silicon-based diode to ensure the power capacity of the entire circuit. The final-stage limiter uses a GaAs diode to increase isolation and ensure fast response speed. The miniaturized broadband coupler is optimized by simulation, and the broadband coupling function is realized in a smaller size. Finally, the power tolerance capability of the limiter is analyzed, and the thermal distribution of the diode is simulated by software.

In this paper, a radio frequency front-end electrically tunable null-forming circuit has been presented. The circuit is composed of quadrature couplers and tunable phase shifters. A quadrature branch-line coupler and a low insertion loss reflective-type phase shifter with a full 360°phase shift range at 6 GHz are simulated as the critical components of the circuit. Finally, an 8-element circuit is simulated at 6 GHz to verify the proposed circuit. The results show that the circuit can successfully construct a tunable null in a full field-of-view with dc bias voltage changing when it is applied to an 8-element uniform linear array. For the best performance element, the depth of the null reaches 24 dB.

A single-layer circularly polarized (CP) substrate integrated waveguide (SIW) horn antenna is proposed. The proposed antenna is the combination of a classic SIW horn antenna and a printed dipole on the same substrate. The distance between the phase centers of the classic SIW horn antenna and the printed dipole contributes to the phase difference between the two orthogonal polarizations. Unlike the traditional antenna array with identical elements, the model in this work is essentially an array consisting of two different elements. The CP generation mechanism of the proposed antenna is discussed from the array perspective and a design guideline is laid down. The CP principle is verified by the simulated and measured results of the proposed antenna. The measured results show that the proposed CP SIW antenna has a 10-dB impedance bandwidth of 8.1% ranging from 10.6 GHz to 11.5 GHz, and its 3-dB AR bandwidth is 4.8% covering 10.73 GHz to 11.26 GHz. The radiation pattern of the proposed antenna is end-fire with a beam parallel with its plane.

In this paper, a compact omnidirectional multiband MIMO antenna is proposed and investigated. Bending the branch of PIFA achieves the miniaturization, and etching a L-shaped slit on the ground extends the working band. The -10dB return loss bandwidth covers two Wi-Fi frequency bands (2400~2800 MHz, 5300~5800 MHz) and 5G communication band (3800~4400 MHz). The central rotatable method is applied to form a four-port MIMO structure. The results show that the antenna achieves a good diversity performance by the polarization diversity. The proposed antenna has a small size of 30 × 30 × 0. 8 mm3, with 360° omnidirectional patterns, promising for the practical applications.

With the increasing complexity of antenna array layouts, the efficient methods for synthesizing the radiation patterns of conformal antenna arrays have been the challenge. In this paper, a generalized method based on convolution neural network is proposed to synthesize the radiation patterns of conformal antenna arrays. Furthermore, the Taylor-based aperture projection method is used to generate the training samples and training labels are designed as some two-channel data matrices. Simulation experiments have been designed with a conformal antenna array, of which the radiation patterns of training set and test set are successfully synthesized. The results show that the trained network has high efficiency and good generalization effect for synthesizing the radiation patterns of conformal antenna array.
