An electronic scanning leaky-wave antenna based on the half-mode corrugated integrated waveguide is proposed in this paper. Electronic scanning is achieved by the employment of varactor diodes. The scanning angle ranges from −24°to +38°continuously at 5.8 GHz, and the gain is greater than 6 dB at all scanning angles. Meanwhile, the circular polarization is achieved by two symmetrical bent slots and the axial ratio is lower than 6 dB. Because of the advantage of half-mode corrugated integrated waveguide, this kind of antenna is compact and beneficial to be applied in some devices without via hole.

When it comes to the realization of RCS reduction, absorptive frequency-selective reflection structure (AFSR) integrated with antenna is effective at building a low-RCS antenna system. In this article, a reconfigurable AFSR using magnetic material is proposed and investigated, which is comprised of a reconfigurable frequency selective surface (FSS) and a frequency-dependent magnetic material (FDMM). The total 11.2 mm thick reconfigurable AFSR realizes switches between broadband absorption from 5 to 8 GHz with −10 dB reflectivity and in-band reflection & out-of-band absorption modes by controlling the ON and OFF states of pin diodes. The proposed structure is simulated and analyzed, where reasonable agreements between these results are observed.

A broadband dual-polarized antenna for base station application is proposed in this paper. The proposed antenna is composed of the main radiator elements, feeding baluns, lower-substrate, and ground plane. Two pairs of quarter-circle dipoles are designed as the main radiator to achieve the dual-polarized characteristic. The devised dipole antenna is excited by the two integrated baluns with convex portions, which is fed by 50 Ω coaxial. Both the main radiator elements and lower-substrate placed on the ground plane are connected by convex portions to ensure structural stability and electrical connection. By simulating and optimizing in the CST, the results show that 22% (4.0-5.0 GHz) impedance bandwidth is achieved. Moreover, high isolation and stable radiation patterns are also obtained over the operating frequency band. With the advantages of concrete structure, high gain, and low cost, the broadband dual-polarized antenna is designed, which is suitable for Sub-6 GHz communication for the base station.

With the development and popularization of intelligent agricultural system, more and more research and attention have been paid to the detection and identification of leaf diseases. We used data sets of apple grey-spot disease, black star disease, cedar rust disease and healthy leaves to study the identification and classification of apple leaf diseases. Image segmentation SVM classifier and ResNet and VGG convolutional neural network model were used for comparison and improvement. In the final experiment, ResNet-18 with fewer layers of ResNet obtained an accuracy rate of 98.5% achieving better recognition effects.

Deep learning has made great progress in the field of inverse design of photonic structures, but the general artificial neural network has the problem of falling into a local minimum in inverse design. We introduce adaptive BN to solve the problem of difficult convergence and large error in a small sampling space. Using this method to predict the photonic structure parameters of graphene corresponding to the double resonance perfect absorption spectrum, a higher prediction accuracy is obtained., showing the superiority of the adaptive BN artificial neural network, and realizing the photonic structure of the on-demand spectral response anti-design.

A microwave sensor inspired by the complementary circular spiral resonant structure is designed in this paper for the non-destructive testing of dielectric material plate. The sensor is designed based on the complementary circular spiral resonator (CCSR) which has two resonance frequencies in the considered frequency band. Frequency shift and variation of $S$11parameter is observed when the sensor is put over materials under testing (MUT). This also happens when the cracks exist in the sample. This phenomenon can be applied for the non-destructive testing of the cracks existing in the dielectric plates. Numerical results are given in the paper for a detailed discussion of the variation of the resonance frequencies and the $S$11parameter for different MUT and the orientations of the cracks.

This paper describes a design of asymmetric coplanar waveguide-fed circularly polarized (CP) antenna for massive machine-type communication in Sub-6 GHz. The asymmetric CPW structure achieves a CP radiation at the upper band. The proposed antenna consists of a modified trapezoid with an extended strip and an L-shaped strip connected to the ground. By utilizing the extended strip, the axial ratio at the lower band is improved. By simulating and optimizing in the CST, the result shows that the axial ratio bandwidth (ARBW) of the antenna is 92% (2.2-6 GHz) and its impedance bandwidth is 100% (2–6 GHz). The antenna covers most of the Sub-6 GHz frequency band, with an overall size of 60 mm × 80 mm ×1 mm. The variation of the gain of the antenna is between 1.3 dBi to 3.7 dBi.
