摘要: 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.

摘要: 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.

摘要: 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.

摘要: A fractal code is provided. The fractal code includes a substrate and a frequency selective surface (FSS). The FSS includes a fractal configuration designed by an iterative procedure, and the fractal configuration is disposed on the substrate. The fractal configuration is formed by a plurality of fractal circle patterns. The radii of the fractal circle patterns decrease by a specified ratio so as to assume a self-similar property, thereby achieving a multi-spectrum property and generating an identification code in frequency domain (FD-ID code). The FD-ID code is applied with space-feed method, and thus a wireless signal is operated in a predetermined band with reflection or transmission radiations, thereby achieving the function of radio frequency identification.

摘要: A loop coupled microwave cavity, which uses a cylindrical cavity as the main body and has a lock hole on the top of the cavity in order to connect to a loop-coupling end formed by bending the long pin of an SMA connector. The long pin of the SMA extends into the cavity through the lock hole so that the top end of the long pin will touch the inner wall of the cavity to receive a microwave signal in TM012 mode to excite the cavity. On the other hand, the coaxial structure formed by the long pin and the lock hole is a quarter-wavelength transformer, so the SMA connector has both loop coupling and impedance transforming functions to increase the Q factor of the cavity. A diminutive sample is inserted into the cavity to perform the cavity perturbation method (CPM).
