Abstract: 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 ).

Abstract: 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.

Abstract: A multiband microwave antenna ( 1 ) is described, which antenna is intended particularly for surface mounting (SMD) on a printed circuit board (PCB) and has a substrate ( 10 ) having at least a first and a second metallization structure ( 11, 12 ), wherein the first metallization structure ( 11 ) has at least a metal area ( 111 ) forming a resonator area and the second metallization structure ( 12 ) has at least a resonant printed conductor structure ( 121 ), thus enabling the antenna to combine the advantageous properties of a PIFA (planar inverted F-antenna) with those of a PWA (printed wire antenna).
