摘要： The invention provides a dielectric resonator oscillator DR, especially for transmission devices whose oscillating frequency may take several values. The oscillator uses two interfering conductors 30 and 31 switched so that they may or may not form a metal plane close to the dielectric resonator DR in order to vary the frequency of the oscillator while using a single resonator. The interfering conductors 30 and 31 are located in the cavity CAV close to the resonator DR and the switching means may or may not establish an electrical contact between the said interfering conductors 30 and 31.

摘要： The invention consists of an antenna array, for the reception of two frequency bands, comprising two pairs of radiating elements and an network for excitation of these elements for the reception of one of the bands. The radiating elements are positioned so as to free the center of the array to allow colocalized reception of the other band. The excitation network comprises hybrid elements so as to introduce a certain phase shift between the radiating elements allowing a dual circular polarization. This network must comply with two constraints: The phase shift introduced between the hybrids must be equal to the phase shift of the hybrid modulo 2kπ k integer. and the length of the line L1 placed between the first hybrid H1 and the first patch PA1 is such that it introduces a phase shift equal to π modulo 2kπ k integer

摘要： The present invention relates to a radiating device intended to receive and/or transmit electromagnetic signals comprising at least two antennas connected by slot and having a common slot. Connection means enable at least one antenna to be connected to processing means of electromagnetic signals. The connection means include two connection lines connected to the processing means. The two lines are terminated by an open circuit and are coupled electromagnetically to the common slot of the two antennas so as to enable a phase difference to be introduced between the electromagnetic signals of the two antennas when the connection is switched from one line to the other by means of a switching device present on the connection lines.
