    摘要: The present invention presents a radiowave antenna system, which includes means for the concentration of said means, like a parabolic reflector or a Luneburg-type lens. A primary feed (14), which receives the concentrated radiowaves, is supported by a tubular or hollow structure (11). This tubular structure (11) houses electronic means (13), such as a low noise converter (LNC). By the arrangement according to the invention, the length of a needed feeder line can be reduced, or such a line can even be avoided. Thereby time and money for the assembly can be saved and performance is improved.

    摘要: Monolithic microwave integrated circuit (MMIC) technology is advantageously used to fabricate microwave circuitry for an antenna-converter system to enable an antenna (102) and its associated converter circuits (109) to be integrated together into a unitary package (100). Small reliable radio frequency (RF) circuits, polarization switch matrix circuits, intermediate frequency (IF) circuits and power and control circuits for the converter are manufactured and integrated onto a plurality of small area microwave circuit disks (120-121) using MIC/MMIC technology. The plurality of converter circuit disks are sandwiched together and directly mounted flat against the back of the antenna to form a unitary package. The disks for the converter circuits are further sized such that the circuit disks fit within an envelope volume defined by the size and shape of the antenna.

    摘要: A pulse radar for operation at 94 GHz and higher frequencies includes an antenna (12), a dipexer (15) and a receiver (25) that are each optically fed, Radio frequency signals may be passed from a transmitter (11) through the diplexer (15) to the antenna (12) and, received by the antenna (12), from the attenna (12) through the diplexer (15) to the receiver (25). The receiver (25) includes two detectors, each consisting of a quartz substrate (137) with an array of four mixers (156). Each mixer (156) has two beam lead diodes (151a, 151b), a coupling line (153), and a quarter-wavelength monopole (155). I.F. output signals are coupled from the mixers (156) through low pass matching filters (157).

    摘要: The invention relates to an antenna for receiving and modulating transmitted signals having a very low power density on the order of below 1 watt per meter squared, at a selected center frequency above 2,000 MHz. The antenna uses a folded planar dipole section having two separated oppositely disposed U-shape elements, each of said elements having a pair of ends. A capacitor is series-coupled between two of the oppositely disposed ends of the elements, and a diode having a high impedance at the selected center frequency is series-coupled between the other two oppositely disposed ends of the U-shape elements. A metallic backplane is mounted parallel to the planar folded dipole section and spaced from the dipole section a predetermined distance selected to reduce the antenna impedance. The impedance of the diode, the shape of the folded planar diode section and the predetermined amount of spacing of the backplane from the planar folded dipole section are all selected to increase the d.c. power output of the antenna.
