    • Electronic devices may be provided that contain wireless communications circuitry. The wireless communications circuitry may include radio-frequency transceiver circuitry and antennas. An antenna may be formed from an antenna resonating element arm and an antenna ground. The antenna resonating element arm may have a shorter portion that resonates at higher communications band frequencies and a longer portion that resonates at lower communications band frequencies. A short circuit branch may be coupled between the shorter portion of the antenna resonating element arm and the antenna ground. A series-connected inductor and switch may be coupled between the longer portion of the antenna resonating element arm and the antenna ground. An antenna feed branch may be coupled between the antenna resonating element arm and the antenna ground at a location that is between the short circuit branch and the series-connected inductor and switch.

    • A test system for characterizing an antenna tuning element is provided. The test system may include a test host, a radio-frequency tester, and a test fixture. The test system may calibrate the radio-frequency tester using known coaxial standards. The test system may then calibrate transmission line effects associated with the test fixture using a THRU-REFLECT-LINE calibration algorithm. The antenna tuning element may be mounted on a test socket that is part of the test fixture. While the antenna tuning element is mounted on the test socket, scattering parameter measurements may be obtained using the radio-frequency tester. An equivalent circuit model for the test socket can be obtained based on the measured scattering parameters and known characteristics of the antenna tuning element. Once the test socket has been characterized, an equivalent circuit model for the antenna tuning element can be obtained by extracting suitable modeling parameters from the measured scattering parameters.
    • 提供了一种用于表征天线调谐元件的测试系统。 测试系统可以包括测试主机,射频测试仪和测试夹具。 测试系统可以使用已知的同轴标准校准射频测试仪。 然后,测试系统可以使用THRU-REFLECT-LINE校准算法来校准与测试夹具相关联的传输线效应。 天线调谐元件可以安装在作为测试夹具的一部分的测试插座上。 当天线调谐元件安装在测试插座上时,可以使用射频测试仪获得散射参数测量值。 基于测量的散射参数和天线调谐元件的已知特性,可以获得用于测试插座的等效电路模型。 一旦测试插座被表征,可以通过从测量的散射参数中提取合适的建模参数来获得天线调谐元件的等效电路模型。
