    Abstract: The present invention relates to techniques to excite a circularly polarized antenna and, more particularly, to a circularly polarized antenna having a QUAD-EMC unit structure. It comprises plural polarized antenna elements; a signal distributor; and a signal coupling element electrically coupled to the polarized antenna elements and electrically connected the signal distributor; wherein, when the circularly polarized antenna is in a transmitting state, the signal coupling element sends the electrical signal from the signal distributor to the polarized antenna elements, and the polarized antenna elements transform the electrical signal into the circularly polarized signal and transmit the circularly polarized signal thereafter; when the circularly polarized antenna is in a receiving state, the polarized antenna elements receive the circularly polarized signal and transform the circularly polarized signal into the electrical signal, and the signal coupling element sends the electrical signal from the polarized antenna elements to the signal distributor.

    Abstract: A notebook computer expansion module is described. The notebook computer expansion module has a support rest, an adjusting handle, a cable, a base, and an adjustable rotational shaft. The adjusting handle coupled to one side of the support rest allows a user to operate conveniently the notebook computer expansion module. The cable is coupled between the adjusting handle and the adjustable rotational shaft for releasing the adjustable rotational shaft so as to rotate the support rest on the base. The adjusting shaft further includes a ratchet fixed on the base, a fixing device, and a fixing plate. The fixing device is coupled to the fixing plate when the fixing device is coupled to the ratchet so as to enhance an engagement strength between the fixing device and the ratchet.
