In order to effectively compress and reconstruct the elemental image array in integral imaging, an improved block compressed sensing algorithm based on integral imaging is proposed. The amount of elemental image data is large and the redundancy is high, so the image is first sampled by interlaced rows and columns, and then the discrete cosine transform (DCT) is performed. The block classification is based on the discrete cosine transform coefficient difference between adjacent pixels in the image block, and is divided into four sub-blocks according to the characteristics of the image. Use different sampling rates to measure samples for different types of sub-blocks. In the reconstruction stage, the total variation algorithm is used to reconstruct each sub-block, the sub-blocks are recombined together to obtain the entire image, and then the image is restored by extracting samples, and finally a complete reconstructed image is obtained. Experimental results show that the use of this algorithm to compress and reconstruct integral imaging images has a good effect.

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 compact ultra-wideband microstrip patch antenna for 5G communication and WLAN is presented in this study. The proposed antenna, consisting of the radiating patch with double cross-shaped slots, circular defects ground structure (DGS) and a rectangular parasitic patch, is printed on the F4B substrate. To achieve the characteristics of broadband and compaction, the double cross-shaped slots and circular DGS are respectively embedded in the radiating patch and ground plane. Moreover, the implication of the parasitic patch realizes the impedance match. The results show that the proposed microstrip patch antenna has the characteristics of broadband and compaction. More precisely, the proposed antenna can operate in the frequency range of 3.28-6.38 GHz, e.g. the relative bandwidth is 64.2%.

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.

A novel circular polarized microstrip 4-unit array antenna based on sequential phase (SP) feed network is proposed in this paper. The proposed antenna is designed to work at 33 GHz. Four square tangential circular polarization patches are connected to the SP feeding network to form a 2×2 microstrip array to achieve better circular polarization performance. A metasurface superstrate is designed above the antenna to improve the antenna gain. Simulation results show that the return loss bandwidth of the proposed antenna for| S11| < −10 dB is 10.1 GHz, and its circular polarization radiation bandwidth is 32.68-38GHz (16.1%) for axis ratio (AR) < 3-dB. With the metasurface layer, the antenna gain can be further improved by 4dB.

This paper presents a dual-band printed phased array antenna fed by microstrip lines operated in 5G millimeter wave band. The reflection coefficients are less than −10 dB for lower band (25.5GHz to 28.5 GHz) and upper band (38.5 GHz to 42.5 GHz) band, respectively and the port isolation is better than 12.8 dB. The proposed design is integrated with parasitic elements, shorting pins and copper frame. The dual-band response is achieved by introducing the I-shaped slot from each patch antenna in the array. The simulated directivity of the array antenna is 14.6 dBi and 14.3 dBi at 27GHz and 39GHz, respectively. The proposed phased array is a suitable candidate for 5G millimeter wave mobile communications due to its merits of broadband, good radiation pattern, low profile, and etc.

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 presents a 1x3 circularly-polarized patch antenna array designated as the Chinese dream antenna array. The three-element array was implemented by using Chinese character-shaped artistic patch antennas (APAs): Zhong-Guo-Meng. The individual patch antennas radiate right-handed circular polarization (RHCP) in the broadside direction, and excited by a one-to-three power divider with equal-power distributions as its feeding network. The CP antenna array exhibits an axial ratio bandwidth and an impedance bandwidth of 310 MHz and 835 MHz, respectively, at a center frequency of 2400 MHz.

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).
