摘要： A method and system for transmitting, and a signal comprising multiple frequency bands from a single slot antenna are disclosed. The system comprises a slot antenna and a micro-electro-mechanical (MEM) switch, coupled to the slot antenna. The MEM switch is opened and closed, thereby changing the resonant frequency of the slot antenna. The slot antenna transmits a first frequency when the MEM switch is open and a second frequency when the MEM switch is closed. The method for transmitting a first frequency and a second frequency from a slot antenna comprises the steps of transmitting the first frequency from the slot antenna, closing a micro-electro-mechanical (MEM) switch coupled across the slot antenna, therein changing the resonant frequency of the slot antenna, and transmitting the second frequency from the slot antenna after the MEM switch is closed. A signal comprising a first and second frequency in accordance with the present invention is transmitted by an array of antennas, wherein the array of antennas comprises at least one slot, the slot being reconfigurable through a RF MEM switch coupled to the slot, by performing the steps of transmitting the first frequency from the slot antenna, closing a micro-electro-mechanical (MEM) switch coupled across the slot antenna, therein changing the resonant frequency of the slot antenna, and transmitting the second frequency from the slot antenna after the MEM switch is closed.

摘要： A microwave ferrite phase shifter wherein three parallel microstrip lines are disposed on a planar ferrite substrate surface opposite a ground plane disposed on an opposite planar surface of the substrate, the lines defining two sets of quadrature E-fields within the substrate to produce a circularly polarized wave therein, the amount of phase shift between the input and output ports of the phase shifter being determined by the magnitude of a magnetic field produced in the substrate in the direction of its axis by a current-carrying coil, for example.

摘要： A wideband, true time delay antenna beamforming network 10 for millimeter wave phased array antennas is disclosed herein. The beamforming network 10 of the present invention includes a laser 30 for generating a beam B of electromagnetic energy. The beamforming network 10 further includes an electro-optic modulator 40 for modulating the beam B in response to an input signal S modulated about a first frequency f.sub.o. A first antenna array 80 generates a first electromagnetic field pattern P by radiating the modulated beam B' in a first direction. The present invention further includes a constrained lens 90 for receiving the first field pattern P and for emitting an antenna driver feed beam F in a second direction in response thereto. An antenna array driver 115 electro-magnetically coupled to the constrained lens 90 by the feed beam F provides a set of signals modulated about the first frequency f.sub.o to drive an antenna array 20.
