Abstract: An radio frequency aerial is capable of remote identifying and applied in a wireless communication apparatus. The radio frequency aerial comprises an identification chip for receiving a radio frequency identification signal, therefore, not only transmitting for general radio frequency communication signal, but also for radio frequency identification signal. Thus, a product data stored in the identification chip can be directly transmitted to an exterior reading device via the radio frequency aerial and radio frequency identification signal without further setting up a chip aerial. In this way, not only is the radio frequency identification and communication ability of the exterior reading device and identification chip improved, but the aerial design of the identification chip and setting cost is simplified.

Abstract: A system for detecting a radio frequency identification tag on an object is provided. The system includes a tunnel having a characteristic linear dimension of a characteristic cross-section and/or having a straight portion and at least one curved portion. The characteristic linear dimension is particularly designed so that the operating frequency of antennas is lower than the cutoff frequency of the tunnel. The leakage of the electromagnetic waves transmitted by the antenna array hence will be reduced. The at least one curved portion is in connection with one end of the straight portion to prevent electromagnetic waves from transmitting out of the tunnel.

Abstract: A commercial system with identifiable reading tags to get useful data is provided. A participation entity, such as a business store, company, non-profit organization, or person, etc., applies registration to a system provider, or the system provider actively provides to create a plurality of identifiable reading tags with unified specification protocol which are fixed on participation entities, such as at least one store, street intersection, public facility, transportation, public used advertisement or product, business card. Every identifiable reading tag has a special label and at least one content tag object capable of representing content data of corresponding participation entities. The data, i.e. corresponding participation entities, content data, and identifiable reading tags, etc., will be integrated into a system database thereby not only benefits to compensate the positioning function with other communication positioning systems but also convenient for users to get a useful data in real time.

Abstract: An anti-counterfeiting apparatus capable of remote identifying is provided. It mainly sets a membrane on an outer package of a product, and an identifying module capable of remote identifying is set on the membrane such that in a process of transmitting, transporting, and managing the product, an outer apparatus is used to read stored product data by the identifying module thereby easier controlling the product. Further, when using and sealing off the product, the identifying module can be destructed or removed at the same time to remove its identifying ability. Although the outer package of the product is refilled fake or counterfeited product to be sold, since the membrane or the identifying cannot be read again, normal product transaction cannot be done thereby easily distinguishing real or counterfeited products.

Abstract: A multi-patch antenna that can transmit radio signals with two frequencies includes a PCB and two stacked-patches. The PCB includes a substrate, a metal layer formed on an upper side of the substrate, and a microstrip line formed on a lower side of the substrate for transmitting radio signals to two slots. The radio signals resonate within the two slots and the stacked-patches, and are then emitted from the stacked-patches in a direction normal to the stacked-patches.
