    摘要: A system for scanning an antenna array of the present invention. The system includes a first mechanism for modulating a desired signal on an optical carrier signal. The first mechanism includes a frequency-tunable optical oscillator with a phase shifter for changing an output frequency of the optical oscillator. A second mechanism employs the optical carrier signal to derive signals having predetermined phase relationships. A third mechanism receives the feed signals and radiates corresponding transmit signals in response thereto to the antenna array to steer the array. In more specific embodiment, the desired signal is a Radio Frequency (RF) signal, and the phase shifter is an electrically controlled optical RF phase shifter. The optical carrier signal includes a first optical carrier signal and a second optical carrier signal. The frequency-tunable optical oscillator includes a first tunable optical oscillator for providing the first optical carrier signal and a second tunable optical oscillator for providing the second optical carrier signal. The first and second optical oscillators include first and second optical RF phase shifters, respectively, that include feedback paths having optical and electrical sections.

    摘要: A millimeter wave (MMW) antenna array includes a continuous transverse stub (CTS) radiating aperture comprising a set of spaced continuous transverse stubs, each having a longitudinal extent. A series feed system is coupled to an excitation source for exciting the stubs with MMW electromagnetic energy having a linear phase progression along the longitudinal extent of the stubs to produce an array beam which can be scanned over a beam scan range by changing the excitation frequency.

    摘要: A reconfigurable wide band phased array antenna for generating multiple antenna beams for multiple transmit and receive functions. The antenna array comprises multiple long non-resonant TEM slot antenna apertures with RF MEMS switches disposed within the slots. The RF MEMS switches are positioned directly within the feed lines across the slots to directly control the coupling of RF energy to the slots. Multiple RF MEMS switches are used within each slot, which allows multiple transmit/receive functions and/or multiple frequencies to be supported by each slot. The frequency coverage provided by the slot antenna has a greater than 10:1 frequency range.

    摘要: A multilayer switching assembly for switching high frequency signals has MEMS structures on a ceramic substrate having a top surface 500, a bottom surface and a plurality of insulating layers (510,512,514). The insulating layers are separated by at least a first conductor 502 and a second conductor 504. The first conductor 502 is connected to a ground potential. The second conductor 504 is separated from the first conductor 502 by one of the insulating layers. The second conductor presents a specific impedance (50 ohms) with respect to the first conductor to high frequency signals traveling on the second conductor. 64 MEMS structures (e.g. 540,708,716,718, 720) are mounted on the top surface. Each MEMS has an input, an output, and a control. The input connected to the second conductor. The output is connected to a coplanar waveguide (508) placed on the top surface (500). The control is connected to the bottom surface. The input to each MEMS is electrically separated from the output and from the control by a third conductor (534,550,532,530) connected to the first (grounded) conductor (502). The third conductor traverses one or more of the insulating layers thereby acting as a shield and precluding the high frequency signals presented to the input from propagating to the output and to the control. The 64 MEMS are arranged in a square 8 by 8 matrix, as well as their controls. High frequency inputs and outputs to be switched by the MEMS are placed on the periphery of the substrate to further enhance the separation of signals. Terminating resistors (50 ohms) are also placed near the periphery.

    摘要: A digital sound file playback reproducer includes a housing in which at least a connection port, a sound source output unit, and a processing unit are provided. The connection port is adapted to connect with an external recording medium having sound filed stored thereon. The processing unit picks up and processes the sound files in the externally connected recording medium, and sends the processed sound files to the sound source output unit. Since the digital sound file playback reproducer does not include an internal memory, a consumer of existing recording media, such as memory cards and USB flash disks, could buy it without wasting money in repeated memory.
