Abstract: A frame sealing adhesive of the liquid-crystal phase shifter is disposed between two transparent substrates, the frame sealing adhesive encloses a first cavity, a first part of the metal-trace layer is located inside the first cavity, and a second part of the metal-trace layer is located outside the first cavity. The second part is disposed on first surfaces or second surfaces of the two transparent substrates. If the second part is disposed on the first surfaces of the two transparent substrates, metal cushion layers are provided between the frame sealing adhesive and the first surfaces of the two transparent substrates. If the second part is disposed on the second surfaces of the two transparent substrates, the first part and the second part are electrically connected by metal via holes provided in the transparent substrates, and the frame sealing adhesive contacts the first surfaces of the two transparent substrates.
