PURPOSE:To calculate the absolute phase of each antenna element, and to make the fluctuation of the power consumption of N-pieces of M-bit phase shifter drivers small without changing a beam direction by adding the phase quantity of the minimum unit of the phase quantity a phase quantity ...
A phased array antenna system formed from an antenna-integrated printed wiring board for performing the functions of a waveguide impedance matching layers, a honeycomb support structure, RF antenna probes, DC logic and RF distribution. The printed wiring board construction of the present invention sign...
摘要: PROBLEM TO BE SOLVED: To smoothen change in the gain of an array antenna in the case of beam scanning by arranging a radio wave absorber at a position on an element antenna board where no element is in existence, thereby suppressing multiple reflection with a radome....
The AWR VSS software provides system designers with the capabilities needed to convert these requirements into hardware specifications and work out the initial design details. Starting with the phased array configuration, the AWR VSS software is able to represent thousands ...

The phasedarray antennahas the advantage of diverse antenna patterns. There may be different flaws in this phased arrayantenna system, which interfere with each other, radiation in the background, and other design and manufacturing issues. Some complex conditions are like the defect factor of the ...
A self-focussing phased-array antenna system for use with a combined intelligence signal (5) and pilot- signal (P) which may lie in the signal band. Each element (1, 3, 5, etc.) of the array has a phase-locked loop (21) which produces a signal ( theta s- theta v) having a fi...
PROBLEM TO BE SOLVED: To provide a phased array antenna system that is facilitated in periodic maintenance, inspection and servicing and ease of replacement of a fault transmission reception module with a new transmission reception module even when the phased array antenna system is in operation.收藏...
A single Antenna can radiate certain amount of power in a particular direction. Obviously, the amount of radiation power will be increased when we use group of Antennas together. The group of Antennas is called Antenna array.An Antenna array is a radiating system comprising radiators and elements...
The present invention provides an antenna array, including a first antenna group, a second antenna group, and a transition band, where the transition band is located between the first antenna group and the second antenna group and is connected to the first antenna group and the second antenna ...
