Abstract: Disclosed is a circular polarized antenna structure, comprising a main body, a protruding portion and a stopping portion, the stopping portion being formed between the main body and the protruding portion. The circular polarized antenna may be disposed to penetrate through the upper and lower surfaces of a base that has a radiation conductor and a grounding conductor disposed thereon respectively, the stopping portion abutting against the lower surface of the base to prevent the main body from coming loose and being detached from the base even if the protruding portion is subjected to a great impact or squeezing pressure caused by an external force coming from the lower surface upwards.

Abstract: A phase shifter includes a substrate, an input part, a plurality of first transmission lines, a plurality of second transmission lines, a coupling part, a controller, and a plurality of output parts. When a signal is fed in a first transmission line, the fed signal is distributed to a corresponding second transmission line via the first transmission line, and an area of the second transmission line shielded by the coupling part is changed by rotating the coupling part through the controller, so as to shift a phase of the signal transmitted by the second transmission line.

Abstract: A phase shifter including a substrate, a plurality of first transmission lines, a plurality of second transmission lines, and a coupling portion is described. After the phase shifter feeds a signal into the first transmission lines, the first transmission lines assign the signal to the second transmission lines. Moreover, the coupling portion moves to change an area of the second transmission lines shielded by the coupling portion, so as to change the phase of the signal transferred by each of the second transmission lines.

Abstract: An adjustable phase shifter for an antenna includes a metal circuit portion, a coupling portion, and a grounding portion. The metal circuit portion is used for receiving a fed-in signal, while the coupling portion is disposed on one side of the metal circuit portion and is disposed at an angle with respect to the metal circuit portion, for controlling a phase angle of the fed-in signal by adjusting the angle formed therebetween. The grounding portion is disposed on the other side of the metal circuit portion in parallel. The structure of the adjustable phase shifter for adjusting the phase angle output by the phase shifter is simple, so as to improving the fabrication efficiency. Moreover, the fabrication efficiency of the adjustable phase shifter is able to be further improved by adopting an attachable impedance matcher, or changing the structure of the coupling portion.
