Title:
ANTENNA DEVICE AND METHOD FOR MEASURING THE ANTENNA
Document Type and Number:
Japanese Patent JP3832234
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain an antenna device capable of reducing abeam direction error by correcting the difference between the set value of real time delay line and actual delay quantity in antenna operation.
SOLUTION: This antenna device is provided with a storage device for storing a correction phase for correcting the difference between the set value of the real time delay line and the actual delay quantity, and an arithmetic circuit for adding the correction phase to the phase set in a phase shifter.
