    摘要: An impedance matching circuit converts between an input impedance of an antenna and a characteristic impedance of a transmission line, such as a coaxial cable. The impedance matching circuit includes a transformer and a lumped circuit. The transformer has a primary side and a secondary side. The secondary side is configured to electrically connect with the antenna. The lumped circuit is electrically connected with the primary side, for converting the input impedance of the primary side to the characteristic impedance. An antenna assembly using the above-mentioned impedance matching circuit is also provided.

    摘要: An integrating SOC capable of integrating a micro-antenna System on Chip (SOC) of integrating micro-antennas comprises an existing radio frequency model, a circuit board and an antenna element to a package of single SOC. The micro-antenna element is formed by using antenna radiated conductor paths composing of a single-feeding end or multiple-feeding ends and multiple-curved paths. Active or passive elements are selected to match up the antenna element and relative circuits, and arranges on the circuit board. Then by using embedding type injection molding or glue-filling modeling, the single SOC is finished by the package of a radio frequency model and an antenna element.

    摘要: A chip antenna has an antenna body and a package. The antenna body has multiple meandered metal lines and is encapsulated with the package. The material of the package is a dielectric composite formed with polymers and ceramic powders, which has a dielectric constant designed for the antenna. The characteristics of the chip antenna are determined by the structures of the antenna body and the dielectric constant of the package. Thus, a requirement for tiny structures in antenna applications can be satisfied.
