Abstract: In this paper, a 4 × 4 wideband linearly polarization (LP) antenna array is proposed by using planar dual-arm spiral structures. Wideband balun structures, composed of microstrip line-fed ...

Abstract: A decoupling method for 2 × 2 circularly polarized (CP) patch antenna arrays is proposed in this letter. Four CP antenna elements surrounded by substrate-integrated waveguide cavities ...

A new technique can generate batches of certain entangled states in a quantum processor. This advance could help scientists study the fundamental quantum property of entanglement and enable them to ...
