Abstract
An antenna includes a first base plate. The first base plate has a phase shifter array area and a bonding area. The first base plate includes a first substrate, a first metal layer, and a first conductive layer. The first conductive layer is made of a high-resistance conductive material. The first metal layer includes conductive pads and phase shifter units. At least some conductive pads are in the bonding area, and at least some phase shifter units are located in the phase shifter array area. The first conductive layer includes bias voltage lines, and one conductive pad is electrically connected to a corresponding phase shifter unit through at least one bias voltage line. At least some sections of one bias voltage line partially overlap with one corresponding phase shifter unit, and at least some sections of one bias voltage line overlap with one corresponding conductive pad.
