In wireless power transfer (WPT) system, the displacement of the receiver coil may cause the problem of efficiency reduction. For this, this paper presents a coil localization method based on the BP neural network, and studies the strategy of using c

Reducing the number of phase shifters by grouping antenna elements into subarrays has been extensively studied for decades. The number of phase shifters directly affects the cost, complexity, and power consumption of the system. A novel method for th

Aiming at the problem of high sidelobe in the pattern of general uniform planar array, the traditional genetic algorithm is used to arrange the uniform array in two-dimensional sparse distribution,which effectively reduces the sidelobe level, but the

In the equivalent frequency-based model, the antenna array gain is utilised to characterise the frequency response of the beam squint effect generated by the antenna array. This impact is considered for a wide range of uniform linear array (

In this study, the problem of blind signal separation for coprime planar arrays is investigated. For coprime planar arrays comprising two uniform rectangular subarrays, we link the signal separation to the tensor-based model called coupled canonical

A dual-polarized paralle-plate waveguide slot array antenna operating at 24.5 GHz band is proposed in this paper. The radiating panel using a 5mm-thick expanded dielectric substrate ( $\epsilon _{r}=1.12$ ) consists of two orthogonally oriented $20\t

In this paper, we present a method for reducing the quantization lobe in a 1-bit beam steering planar array antenna. The method is inspired by reflectarray feeding in such a way that as we move away from the center of the array, the phase becomes mor
