发明名称 Tuneable PCB antenna
摘要 An antenna and antenna manufacturing process for an antenna configured for at least one of transmission or reception of electromagnetic waves with respect to a surrounding environment, the antenna having an antenna element positioned in metal trace on a carrier body, antenna element being isolated from an electrical ground of the antenna. The antenna comprises: at least one predefined removal portion positioned in the carrier body for containing a removal fraction of the antenna element, such that the carrier body located outside of the predefined removal portion is configured to contain the remainder fraction of the antenna element; and a weakness pattern in the carrier body about at least part of the periphery of the at least one predefined removal portion, the weakness pattern configured for predisposing the carrier body to break along the weakness pattern upon application of force, such that the at least one predefined removal portion and corresponding removal fraction would be separated from the antenna upon application; wherein the separation of the predefined removal portion and corresponding removal fraction provides for modification of at least one tuning parameter of the antenna having the remainder fraction as the tuned antenna element.
