    摘要： An antenna positioner is provided for use in an anechoic chamber to enable the radiation pattern of an antenna under test to be measured. A vertically disposed and selectively rotatable azimuth rotator pedestal is positioned in the anechoic chamber and a support is mounted on the pedestal for rotation therewith. A roll-axis shaft is mounted on the support for rotatably supporting the antenna under test. The roll-axis shaft rotator is positioned outside the anechoic chamber and has a horizontally disposed and horizontally movable connecting rod which is selectively movable into the chamber for connection to the roll-axis shaft to incrementally rotate the roll-axis shaft and the antenna under test.

    摘要： A single antenna element with a switchable extension may be used to change the size of the radiating surface and provide an antenna that has two or more separate center frequencies. The range of frequencies that may be tuned by the antenna is enhanced, while maintaining relatively low complexity tuning and matching circuitry. Switching for the extension is performed by a switching element that is located at the point of connection of the extension to the antenna element. A control line supplies a control signal to the switching element to enable and disable the extension. The control line is positioned in close proximity to the antenna element to enhance coupling between the antenna element and the control line.
