Enhancing MIMO Array Imaging Quality

For radar imaging, resolution and dynamic range are two critical metrics to measure image quality. MIMO array exploits the spatial diversity of transmitters and receivers to achieve high cross-range resolution with fewer antennas than array-based imaging.<br/> Generally, to make full use of the sparsity, at least the transmit array or the...

mm-Wave Heatsink Antenna Array Design for Low-Sidelobe and Low-Temperature

The development of fifth-generation (5G) technology is the beginning of a rapid transition in the world of wireless communications. Gbps data rates, minimal latency, and good connectivity are the ultimate aims of 5G. To achieve them, 5G systems employ the mm-Wave frequency band which has a frequency range above 24GHz and so allows for higher...

A Toolbox of Subarrays for Optimizing Wide-Angular Scanning Arrays Using Trade-Offs between Scan Loss and Side Lobe Level

A novel approach is proposed for building a planar array derived from linear arrays using a toolbox of different types of subarrays located parallel and perpendicular to the linear array axes. The array design assumes constant element patterns and focuses on rectangular array applications with one dimensional, wide-angular beam scanning....

Use of subarrays in linear array for improving wide angular scanning performance

The scanning performance of wide-angular scanning linear arrays is primarily degraded by the limited angular profile of the employed elements' patterns. This paper introduces an innovative strategy for compensating this degradation by using subarrays. Our design uses a uniform linear array with half-wavelength spaced elements, supplemented by...
