Title:
ACTIVE PHASED ARRAY ANTENNA AND ANTENNA CONTROLLER
Document Type and Number:
WIPO Patent Application WO/2000/036702
Kind Code:
A1
Abstract:
An active phased array antenna, as shown in the figure, comprises antenna patches (106a to 106p) arranged in a matrix at regular intervals in both the line and row directions on a dielectric substrate, a grounded power feeding terminal (108) to which a high frequency power is supplied, first control voltage generating means (111) for generating a line direction directivity control voltage, and second control voltage generating means (112) for generating a column direction directivity control voltage. The antenna patches (106) are connected to the power feeding terminal (108) by a power feeding line (121) branched from the power feeding terminal (108), and phase shifters (107) constitute part of the power feeding line (121). Such an active phased array antenna has a simpler structure, has a continuously changeable antenna directivity characteristics, and is produced at low cost.
