    摘要: An axial-winding motor includes a stator and a rotor. The stator has a winding assembly, a first magnetic-conducting plate and a second magnetic-conducting plate. The first and second magnetic-conducting plates are coupled with two ends of the winding assembly in an axial direction of the winding assembly. The first magnetic-conducting plate includes a plurality of first pole pieces on an outer periphery thereof, and the second magnetic-conducting plate includes a plurality of second pole pieces on an outer periphery thereof. The rotor is rotatably coupled with the stator and has a plurality of magnetic pole faces facing the stator. One of the first pole pieces is at least partially overlapped with adjacent one of the second pole pieces in an axial direction of the stator.

    摘要: Two PIFAs substantially perpendicular to each other have feed points facing each other and ends connected. A phase transformer is coupled to one of the PIFAs to produce a phase difference of 90 degrees in electric fields generated by these two PIFAs so as to generate circular polarized waves.
