Impedance converter of antenna, antenna module, and image display device

The utility model provides an impedance converter of an antenna, an antenna module and an image display device. An impedance converter of an antenna includes a first port receiving power from an antenna driving integrated circuit, an impedance modulator connected with the first port to convert impedance, and a second port connected with the modulator and configured to perform feeding for an antenna unit. The impedance of the second port is higher than that of the first port. The antenna characteristics are improved by preventing impedance mismatch by the impedance modulator. 本实用新型提供一种天线的阻抗转换器、一种天线模块以及一种图像显示装置。天线的阻抗转换器包括从天线驱动集成电路接收电力的第一端口、与第一端口连接以转换阻抗的阻抗调制器以及与调制器连接并且被配置为执行针对天线单元的馈电的第二端口。第二端口的阻抗高于第一端口的阻抗。通过阻抗调制器防止阻抗失配而改善了天线特性。
