Abstract
The invention discloses a 1-bit phase reconfigurable variable polarization all-metal reflective array antenna unit, and relates to the technical field of communication antennas. The antenna unit is an all-metal structure, including: a metal base, a rotatable metal turntable is provided on the upper surface of the metal base, and two first fan-shaped metal steps and two second fan-shaped metal steps are arranged on the metal turntable. The ladder and two third fan-shaped metal ladders, the central angle of the sector formed by the projection of the fan-shaped metal ladder on the xoy plane is 45°, and the two first fan-shaped metal ladders are arranged oppositely, and the two second fan-shaped The metal steps are arranged oppositely, and the two third fan-shaped metal steps are arranged oppositely. The antenna unit can respectively realize 1-bit phase reconfigurability and polarization reconfigurability, and has low dielectric loss.
Description
technical field [0001] The invention relates to the technical field of communication antennas, in particular to a 1-bit phase reconfigurable variable polarization all-metal reflective array antenna unit. Background technique [0002] A reflectarray is a high-gain antenna. Because of its extremely low profile, easy-to-process structure, high radiation efficiency, and low cost, reflectarray antennas are widely used in various communication scenarios. Compared with the traditional phased array, the reflectarray that uses the space feeding method for feeding does not need a complicated feeding network, which greatly reduces the manufacturing cost and complexity of the antenna. Compared with the transmission array antenna that also uses space feeding, the reflectarray usually has a simpler unit structure, and the feed input space of the reflectarray and the radiation beam exit space share the same space, and the space utilization rate has been greatly improved. The phase of each...
