Under near-field conditions, spatial undersampling leads to grating lobes in the sparse multiple-input multiple-output (MIMO) array results. A fast zero migration algorithm is developed in this communication for suppressing the grating lobes. In our method, resampling in the wavenumber domain is first achieved on the received data, and then, the fast inverse Fourier transform (FT) and compensation on the image domain is leveraged for achieving zero migration of transceiver array. By applying apodization on the zero migration result, zero spreading is equivalently achieved and thus alleviate the influence of grating lobe spreading under near-field conditions and avoid the ghosts in the imaging results. Benefit from its fast FT-based processing scheme, the method achieves a reduction in computational complexity from O(${N} ^{4}$ ) to O(${N} ^{3}$ logN). Both simulated and measured data validate the superiority of the method in effectively suppressing grating lobes and improving the processing efficiency.

A circuit-informed neural network (CINN) is proposed for broadening the bandwidth of substrate-integrated waveguide (SIW)-fed slot antennas. The proposed approach optimizes the structural parameters for matching multiple stub pairs (SPs) efficiently by combining circuit knowledge and a well-trained artificial neural network (ANN) for single SP. The CINN significantly reduced the computational costs of optimization, dataset construction, and training. Experimental results illustrated the effectiveness of the proposed CINN in achieving a wide impedance fractional bandwidth of 43%. This approach features strong generalization capabilities, making it widely applicable to various SIW antennas with diverse structures and varying numbers of SPs.
