Impedance Matching Circuit and antenna Assembly using the same

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.
