The invention relates to a
wireless communication technology, and particularly discloses a fast
antenna matching method. The method comprises the following steps: step S1, measuring
inductance Lant amount, a loss resistance Rant value and a
parasitic capacitance Cant value of an antenna
equivalent circuit; step S2, adjusting the antenna quality factor Q of the antenna circuit, calculating a series resistance RQ value of the adjustment Q value of the antenna circuit and a normalized impedance (the formula is as shown in the specification) value of the antenna circuit; step S3, calculating conjugate normalized impedance (the formula is as shown in the specification) of an
equivalent circuit of a
low pass filter circuit, and step S4, adopting a
smith chart to perform conjugate match on the calculated (the formula is as shown in the specification) and (the formula is as shown in the specification). According to the fast
antenna matching method disclosed by the invention, an antenna circuit test process is processed by using the
smith chart and a corresponding matching calculation flow, therefore no network analyzer is needed in the test process, and the matching work can be accomplished just by using one LCR electronic tester, thereby reducing the
machine cost, and ensuring faster, simpler and more visual and understandable matching work.
