Abstract A high‐power, high‐isolation, dual‐polarised planar phased array antenna is presented. Based on a multi‐layer microstrip structure, two sets of polarisation ports are fed through orthogonal slot coupling, achieving high isolation and

Abstract This paper introduces the subarray partition based on the sparse array weighted K‐means clustering method, which extends the conventional K‐means clustering method through the inclusion of a weight matrix approach. This matrix is derived

Abstract This letter presents a Ka‐band low‐cost microstrip line phase shifter based on liquid crystal (LC) technology. Furthermore, a sum‐difference beamforming antenna array based on the LC phase shifter is designed. The phase shifter is comp

An inverted-L monopole radiating element is proposed for antenna-in-package modules at the 151.5-164 GHz band. Its radiation pattern is half-isotropic and is well-suited for phased arrays for mobile communications. The ideal inverted-L monopole is an

In this paper, a novel ultrawideband phased array is presented based on exponential curve modified dipoles. A tightly-coupled exponential curve modified dipole arm is used to extend the operating bandwidth with a simple coplanar strip structure, whic

A low-profile dual-polarized magneto electric (ME) dipole antenna configuration implemented on standard multilayer PCB technology is here reported. The proposed radiator is conceived for dual-polarized 28 GHz 5G phased array applications. Wideband op

Distance sensors are important for mobile robots to perceive surrounding environment. Typical sensors like LiDARs and depth cameras have been widely used, yet each has its limitations, such as LiDARs’ relatively high cost, depth cameras’ limitati
