    摘要: A device for dynamic impedance matching between a power amplifier and an antenna, having a circulator (210), which routes a signal received from the power amplifier (10) at a first port via a second port to the antenna (30) and diverts the signal reflected at the antenna (30) and received at the second port through a third port; and a controllable matching network (24, 240, 250); is characterized in that a directional coupler (200) diverts a proportion of the signal traveling from the power amplifier (10) to the antenna (30), from which the magnitude and phase of the signal may be derived, to a signal detector (220); and the circulator (210) routes the entire signal reflected at the antenna (30) into the signal detector (220); wherein the signal detector (220) passes the magnitude and phase of both the signal traveling to the antenna (30) and the signal reflected at the antenna (30) to a controller (230), which evaluates the information received from the signal detector (220) in order to determine the present impedance value of the antenna (30) and to correct the controllable matching network (24, 240, 250) having active and passive components in accordance with the determined impedance value of the antenna (30).

    摘要: The invention relates to an antenna comprising a dielectric substrate (1) and two resonant printed wiring structures, more particularly for use in high-frequency and microwave domain. On an end face of the structure (2) is arranged along a first edge and on an opposite, second edge of the same end face a second printed wiring structure (3). The arrangement of the printed wiring structures provides that resonances are developed which make the use of the proposed antennas in the four separate GPS, DCS/PCS, UMTS and Bluetooth applications possible.

    摘要: The invention relates to a miniaturized phased array antenna with a plurality of individual radiator elements (10xy), which antenna is designed in particular for use in the microwave frequency range. The antenna is characterized in particular that the radiator elements (10xy) are each aligned in dependence on their positions in the array so as to achieve a current distribution over the antenna as determined for a desired antenna characteristic. This renders it possible to realize a very strongly miniaturized antenna without the efficiency of the antenna being appreciably reduced.
