This paper introduces the concept of the sparse array into the design of a wide-angle scanning phased array to obtain the low sidelobe level (SLL).The adopted array element is a half-mode substrate integrated waveguide slot apunisw2 array, which can radiate a high-gain and wide-beam pattern in the E-plane.A 16-element phased array with an optimized

Low-Earth-Orbit (LEO) satellite networks have the advantage of global internet coverage and low latency, and they have enjoyed great success in the past few years.In cubs foam finger LEO satellite networks, laser-based inter-satellite links (ISLs) are widely employed to achieve on-board data relay, and further to provide high-capacity backhaul worl
