In this paper, the human arm is selected as the research object to study its path loss for wearable application. Two same all-fabric microstrip antennas with microstrip line feed are designed using conventional fabric materials and conductive fabrics, where the less electromagnetic wave propagate along the arm than that of the dipole antenna etc. The measured S21 parameter of same curvature in free space and on the arm for both are compared and analyzed, and then get the path loss for the arm characteristics. Finally, the curve fitting technique is used to fit these two measured curves according to the fundamental of the path loss. The results show that the path loss index in free space at the resonance frequency of 5.8GHz is 2.23, while it is 1.03 on the arm.

An artistic antenna shaped like Chinese character ‘Shan’ was proposed in this work. ‘Shan’ serve as a radiation patch and the feed point is placed on the right side of the re-radiation patch. The transmission zero of the proposed antenna was at 3.51 GHz and the impedance bandwidth was 25 MHz (3.495 GHz-3.520 GHz). The simulation maximum gain of the antenna was 5.735 dBi. In addition, the proposed antenna could also be redesigned as a dual-band antenna. Thus, the proposed antenna shaped like ‘Shan’ has a promising potential for the application of 5G communication.

The traditional Fourier algorithm cannot fix the problem of non-stationary noise deduction for MEMS-IMU, therefore this article uses Empirical Mode Decomposition (EMD) algorithm to denoise the signal. In this article, Extreme Learning Machine (ELM) is combined to reduce the influence of end effect in the decomposition. First, the MEMS-IMU simulate signal generated by matlab is taken as the test object, and EMD as well as ELM extension decomposition are carried out for it respectively. The decomposition noise reduction effect is compared and analyzed to study the role of EMD and ELM in the process. Second, carry out a test on the authentically measured MEMS-IMU signal. In de-noising the MEMS-IMU simulate signal and authentic signal, we can analyze the noise deduction effect and observe the changes of parameters related to random error. The results show that the method based on ELM and EMD can achieve good noise reduction effect for MEMS signal.

For TV/FM based passive bistatic radar (PBR), due to the narrow bandwidth and low frequency of the transmitted signal, there are usually multiple targets located in the same range-Doppler bin, so it is necessary to carry out multi-target DOA estimation. This paper proposed a method of multi-target DOA estimation based on sparse reconstruction for TV/FM PBR. At first, clutter cancellation algorithm and range-Doppler cross correlation are utilized to remove DMC and improve SNR of targets. In order to acquire targets' DOA, signals in targets ‘range-Doppler bin are then reconstructed in spatial domain using sparse reconstruction algorithm. Finally, the performance of this method is studied using numerical simulation.

This paper proposes a dual-port dual-band smartwatch antenna with polarization diversity. The antenna is located on the frame of smartwatches and realized by composite right/left handed-transmission line (CRLH-TL). The overall model has a cylindrical shape, and the diameter and the height of this smartwatch antenna is 33.6 mm, and 6.8 mm, respectively, which is can be integrated in the framework of most smartwatches. The two ports can excite orthometric current distributions to realize the polarization diversity. The CRLH-TL is loaded on the annular ring, to realize the 2.4/5.8 GHz dual-band operation. A metallic plate is located at the back of the proposed smartwatch antenna to simulate the backed shell of smartwatch. Besides, a wrist model is considered in analyses to evaluate the on-body performance of the proposed antenna.

A simple system for the measurement of scattering parameters is presented utilizing an open Transverse Electro-Magnetic (TEM) cell. The scattering parameters are simulated in the principle of Finite Differences Time Domain (FDTD). Meanwhile, a classical slot Frequency Selective Surface (FSS) was simulated in the proposed TEM cell, and the results are in greet agreement with the full-wave simulated results in unit cell way. The simulation result shows a good field uniformity and low reflection in the frequency range of 1 to 8 GHz, which may be applied in absorptivity measurement of absorber, transmission and reflection coefficient of FSS, Frequency Selective Rasorber (FSR).

This paper presents a wideband high-efficiency circularly polarized (CP) phased array antenna with low profile for Ka-band satellite. The antenna introduces a common ground structure for both microstrip line and circular patch to reduce the profile and make the antenna easily integration. In addition, complementary metal grids and defective ground effectively reduce the coupling between units to improve the gain of the antenna. At the same time, the sequential rotation technique is applied in the antenna array to expand the axial ratio bandwidth. The profile of the antenna is 0.076λ0 (λ0 is the wavelength in free space). The impedance bandwidth for S11<-10 dB is 15.8%, and the AR is below to 3dB in the whole operating band. The radiation efficiency can reach more 90% over the whole band.

The electrocardiogram (ECG) is a weak bioelectrical signal which is susceptible to noise, hence, the noise cancellation plays an important role for practical applications. Before that, various algorithms have been proposed to ECG denoising. However, the above efforts do not involve the nonlinear distortions, which may encounter in cancellation model. To address this problem, we propose a functional link artificial neural network sign algorithm (FLANN-SA) based on Griffith variable step size (VSS). Compared with existing algorithms, the proposed algorithm exhibits the improved performance than existing algorithms in terms of signal noise ratio (SNR) and the mean square error (MSE).
